A propane tank cover is a fitted shelter that wraps your RV’s 30 lb LP cylinders to keep rain, snow, road salt and UV off the steel. Searching for the best RV propane tank covers for winter is mostly a fitment question, and fitment is where most owners go wrong. Buy the wrong size and it flutters at highway speed or will not clear your tongue jack.
We spent weeks comparing ten covers that show up again and again on RV tongues, from hard molded polypropylene shells to diamond-plate vinyl and 600D Oxford fabric. The hard shells win on impact and cold, the soft covers win on price and quick valve access, and the difference matters more in northern winters than most product pages admit. If you also run propane gear on a patio, our picks for the best propane fire pits for patios follow the same cold-weather logic.
We also answer the question that sits underneath every product page: should you cover your propane tanks at all, or bring them inside? The honest answer depends on your climate, how the tank is mounted, and whether you still plan to run appliances in the cold. We get into it before the reviews, because the wrong call there makes any cover pointless.

Should You Cover Your Propane Tanks in Winter?
Yes, in most climates. A cover keeps rain, snow and UV off the tank, which is what actually drives corrosion, and adds a layer of insulation that slows temperature swings. It will not stop a tank from going cold in extreme cold, and you must keep the valve and regulator reachable. Never cover a propane tank while performing a leak check.
Here is when covering is the right call and when it is not:
Cover your tanks when the RV sits outdoors for weeks or months, when you run on a coastal or salted road, when the tanks catch direct desert sun, or when you see bare metal or surface rust starting to appear on the cylinder wall.
Skip the cover when the RV is parked inside a garage or storage building, when you already pull the cylinders out for winter, or when you need to run a leak check or swap a tank in a hurry and cannot reach the valve through the shell.
There is a second reason to cover that surprises people. Propane expands as it warms, and a cover insulates the tank from direct sun, keeping the temperature of the metal more stable across a day. That stability is good for the steel and for the paint on it. The same logic explains why paint on a tank fails: the shell expands and contracts with temperature swings and with cycling from empty to full, so ordinary paint will not stay adhered.
What a cover will not do is stop a regulator or a supply line from freezing. That problem lives inside the cabinet, not outside on the tongue. Full-timers running below freezing typically deal with it by adding skirting, using heat tape on the lines, and leaving cabinet doors open to let interior air move. Filling your tanks before a cold snap is the cheapest fix of all, because an empty cylinder has nothing left to deliver when the pressure drops.
Owners of horizontal ASME tanks face a harder version of this. TrailManor forum members point out that purpose-built covers for horizontals are effectively unavailable, so the usual choice is an enclosure, a repaint, or bringing the tank indoors for the season. Our guide to large-tank humidifiers for whole homes covers the indoor half of that decision for anyone who ends up storing fuel-fed equipment inside.
1. BroilPro 20-Pound Steel Cylinder Cover – Proven Heavy-Duty Vinyl Fit
BroilPro Accessories Propane Tank Cover Fits 20-Pound Steel Propane Cylinder
Heavy duty vinyl with 300D polyester lining
Water resistant
13 x 13 x 17.5 inch
Fits 20lb steel cylinders
Pros
- Heavy duty vinyl over a 300D polyester lining
- Accurate fit for standard 20lb steel cylinders
- Water resistant and blocks sun fade
- Low profile footprint suits tight tank racks
Cons
- Soft shell gives less impact protection than molded covers
- No dedicated valve access hatch
- Single tank size only
This is the cover we kept coming back to during testing, mostly because the fit is so consistent. At 13 inches square by 17.5 inches tall it drops over a standard 20 lb steel cylinder without wrestling, and the hook and loop closure means no bolts, no nuts and no tools. On a cold morning with gloves on, that matters more than any spec sheet.
The build is a heavy duty vinyl outer with a 300D polyester lining underneath, which is a smarter construction than a single layer of thin vinyl. It sheds rain and road spray, and it blocks the UV that starts the paint letting go on the cylinder wall. Reviewers consistently call out the accurate 20 lb steel fit and the quick install as the reasons it stays in service.
The review base is the reason we made this the first pick. A 4.7 average across more than 4,200 reviews is a lot of real winters, real salt and real highway miles reported by owners, and the negative feedback clusters in one place: there is no valve access hatch, so swapping a cylinder means pulling the cover off.
For winter storage on a tongue where the tanks stay put, that trade is fine. For an RV that runs cold-weather heat or cooking, it is an annoyance. The cover measures 13 inches by 13 inches by 17.5 inches and weighs just over half a pound, so it is easy to lift one handed while kneeling in slush.
Check the 20 lb vs 30 lb fit before you buy
This cover is sized for 20 lb steel cylinders. If your rig runs 30 lb tanks, the body will sit loose and the closure will not draw the fabric tight, which is exactly how wind gets underneath a cover. Dual 30 lb setups should look at the Flame King dual 30 lb hard shell or the Camco 50514 instead.
Also confirm that your cylinder is the standard steel type with a collar handle. Very old or very tall fittings can push past the 17.5 inch height and stop the vinyl from seating properly around the shoulder.
Know what you are giving up with a soft shell
Vinyl over polyester blocks water and sun, not rock strikes. If you do most of your driving on gravel forest roads or highways with heavy truck traffic, a molded hard shell takes that abuse far better. A soft cover is the right answer for storage and for paved-route winter living.
The lack of a valve hatch is the other limitation. Budget a few seconds of extra work every time you change tanks, and keep the cover where you can grab it without crawling under the trailer.
2. Flame King Dual 20LB LP Cover – Hard Shell for Two Small Tanks
Flame King Dual 20LB LP Propane Tank Light Plastic Heavy Duty Cover for RV, Travel Trailer, Camper – Black
Molded polypropylene
29 x 14 x 19.5 inch
Fits two 20lb tanks
Side port plus two top hatches
Pros
- Hard shell shrugs off rock strikes and road debris
- Side access port reaches the regulator without removal
- Two individual top hatches for each valve
- Snug form-fitting profile over two tanks
- Backed by a 1-year manufacturer defect warranty
Cons
- Two-piece design can bind beside the trailer jack
- Requires assembly with nuts and bolts
- Plastic can feel thin beside premium hard shells
Dual 20 lb tanks are awkward because the two cylinders sit at slightly different heights and there is not much structure between them. This molded polypropylene cover was shaped around that reality, and it measures 29 inches long by 14 inches wide by 19.5 inches tall to swallow the pair as one unit.
The access design is the reason it earns a place here. A side port lets you view and adjust the regulator without pulling the cover off, and each cylinder gets its own top hatch. When you are running appliances through a January cold snap, not having to dismantle a shell to check a valve is worth more than the price difference against a fabric cover.
Polypropylene is the right material for a northern winter. It stays rigid in cold the way soft vinyl stiffens and then cracks along its seams, and it does not soak up water on a wet tongue. Reviewers report roughly 20 minutes of assembly with the included hardware, and the fit looks OEM-clean once the nuts are tightened.
Watch one thing. The two halves can bind if one sits tight against the trailer jack, and a few owners added their own nylon safety tie to guard against wind lift at highway speed. If your tanks are tucked close to the jack, measure the gap before you order.
Confirm it clears your tongue jack and chain
A 14 inch wide shell is comfortable on most A-frame tongues but tight on a V-nose or a tongue with a heavy jack bracket. The cover is described as fitting RVs, trailers and dual-tank setups, but the jack clearance is a rig-specific measurement you need to take yourself. Pull a tape measure, not the guess from the listing photo.
The Flame King warranty is a limited 1-year manufacturer defect warranty, and it is void if the cover is purchased from a seller other than Flame King or Amazon Retail. Buy through the normal channels so the warranty actually applies to you.
Decide whether soft or hard suits your season
If the RV is parked and untouched from November to March, a soft cover does the job and costs less. If you travel through winter, run into service stations regularly or park where grit and road salt are heavy, the polypropylene shell earns its extra cost through impact resistance alone.
Polypropylene can stiffen in extreme cold too, so do not drop the assembled cover onto a frozen tongue at full force. Carry it in and set it down.
3. Flame King Dual 30LB LP Cover – Hard Shell for Standard RV Setups
Flame King Dual 30LB LP Propane Tank Light Plastic Heavy Duty Cover for RV, Travel Trailer, Camper And Recreational Vehicle – Black
Molded polypropylene
Fits two 30lb tanks
Multiple access ports
7.1 pounds
Pros
- Molded polypropylene handles road rock and rough travel
- Two top ports plus side ports reach valves and the tank selector
- Bolts and locking nylon nuts hold better than riveted factory covers
- Cleans easily and blocks sun-fade grime
- Common upgrade when moving from 20lb to 30lb tanks
Cons
- Arrives in flat sections that must be bolted together
- Included black bolts can discolor with rain exposure
- Access ports can make gauges and switch indicators harder to read
Most full-size travel trailers and Class C motorhomes run two 30 lb cylinders, and this is the shape that fits. The Flame King dual 30 lb shell is a 4.7 average across 1,092 reviews, which puts it with the strongest-rated covers in this group and well ahead of the soft vinyl options on durability complaints.
What stands out is the hardware. It bolts together with bolts and locking nylon nuts rather than rivets, and that is the single biggest upgrade over a factory cover. Rivets work loose on washboard roads, and a cover that rattles off a tongue in February is a cover you will find in a ditch.
Access is handled with two top hatches and side ports, which reach the valves and the tank selector without removing the shell. Several owners note the ports can make a gauge or a red tank-switch indicator harder to read at a glance, so plan to open the panel when you actually need to check a reading rather than relying on it from a distance.
It weighs 7.1 pounds. That is real weight in your hands, but it is also a rough indicator of how much plastic you are getting compared with the vinyl covers below, which weigh about a pound or less.
Upgrade the bolts before the first wet month
The most repeated advice in the reviews is to swap the included black bolts for stainless hardware and add fender washers. Black bolts stain and eventually corrode at the weather seals, and a pitted bolt head is a miserable thing to turn with cold hands. Spend a few minutes on this before the cover ever sees a tongue.
Assembly is the other time investment. The cover arrives in flat sections, so budget an evening the first time. Owners also recommend adding a small tie-down to guard against wind lift at speed, which is cheap insurance on a highway route.
Understand what the ports do and do not give you
Ports are for checking, not for changing. A regulator adjustment or a quick valve check is realistic through a port. Swapping a cylinder or running a full leak check is not, and for that you still need to remove the cover, which is the correct, safe behaviour.
If you plan to run propane appliances while the cover is on, check that your regulator and manifold sit within reach of a side port before you commit. That is the single most useful thing to verify on your own rig.
4. ADCO 2113 Double 30 Vinyl Cover – Shaped Fit in Tight Spots
ADCO 2113 RV Propane Tank Cover,White,Double 30
Deluxe heavy-duty vinyl
UV protection
Double 30 fit
16 ounces
Pros
- Molded nylon zipper with a pressed wood top holds its shape
- Hollow bead welt cord and elastic shock cord give a tailored fit
- Deluxe vinyl with UV protection
- Available across several tank configurations
Cons
- Lowest average rating in this group at 4.1
- Vinyl and stitching degrade faster than hard shells
- Zipper and wood top are absent on single-tank models
Most soft covers are a bag that drapes. The ADCO 2113 has structure: a molded nylon zipper at the top and a pressed wood panel that holds a defined shape instead of collapsing onto the cylinder collar. At 16 ounces it is light enough to lift one handed, and the hollow bead welt cord plus elastic shock cord pull the skirt tight around both tanks.
It is also one of the few covers here that fits where a hard shell cannot. On a V-nose trailer, a tongue with a low-profile box, or a rig where a tall molded shell fouls the jack, this slim vinyl profile will sit flat where a rigid cover would not.
The rating spread is the honest part of this review. A 4.1 average across 1,169 reviews with 9 percent one-star feedback makes this the least even-keeled cover in the group. Fans like the shaped top and the neat tailored fit. Critics focus on vinyl and stitching giving up in direct sun and heat, and an RV parked in Arizona will test those seams harder than one parked in Vermont.
It is listed in polar white, carries UV protection, and is water resistant rather than waterproof. The double 30 configuration fits a pair of 30 lb, 7.5 gallon tanks, and the same family comes in single 20, double 20 and double 40 sizes if your rig differs.
Know that soft means replaceable
Treat a vinyl cover as a consumable. Expect the stitching and the zipper to give out before a polypropylene shell does, and inspect the seams each spring for chalking, UV bleaching and split thread. Owners replacing faded soft vinyl after a season of direct sun is a recurring theme on RV owner groups.
If your RV lives under a carport or an awning, a soft cover has a much easier life and this one becomes a strong option. If it sits in open sun year-round, favor the hard shell instead.
Check the single-tank version carefully
The zipper and pressed wood top are not included on single-tank models in this family. If you are covering one cylinder and want easy valve access, verify the single version includes the hardware you need before ordering, or you will be cutting a flap yourself.
Also allow for the fact that a soft skirt is easier for wind to catch. A ground anchor tab or a strap to the tongue frame takes care of that, and it costs nothing extra.
5. Camco 40578 Single Tank Cover – Quickest Valve Access
Camco Single Camper/RV Propane Tank Cover – Features a Removable Top Panel & Heavy-Duty Polymer Design – Fits 20lb. Steel Single Tanks (40578)
UV-protected heavy-duty polymer
Removable top panel
13.38 x 18.69 x 19.44 inch
Fits one 20lb tank
Pros
- Removable top panel gives fast access to gas and changeover valves
- UV-protected polymer built to take road debris
- Light enough at 2.9 pounds to lift one handed
- Clean black finish that matches most tank racks
Cons
- Covers a single 20lb tank so dual rigs need two
- Loose top panel can lift in highway wind
- Less form-fitting than molded twin covers
Access is the whole idea here. The Camco 40578 has a removable top panel, so you lift the lid, check or adjust the valve, and drop it back. No ports, no disassembly, no tools. For an owner who runs appliances in cold weather and wants to check a valve without a flashlight in their teeth, that is the feature that sells it.
Construction is a heavy-duty UV-protected polymer, which is the right call for a cover whose job is blocking sun and debris. It measures 13.38 by 18.69 by 19.44 inches and fits one 20 lb steel tank. The black finish is the low-key look most owners want on a tongue.
Two practical points. This is a single-tank cover, so a dual-tank trailer needs two of them, and on a dual rig the two shells side by side will not look as clean as one molded twin cover. Second, the removable panel is a loose panel, and a recurring review theme is that it lifts in highway wind if it is not secured.
That is an easy fix. Run a short bungee or a strap from the panel to a tongue frame anchor. It takes a minute and it removes the only complaint that really matters on this cover.
Decide single versus dual before you measure
Single covers make sense when you only ever run one cylinder, when you want the option of swapping a spare tank in quickly, or when your tongue is too narrow for a wide twin shell. They are a poor fit for a full-time rig that alternates between two tanks, because you would need two covers and twice the storage.
Check your tank height too. At 19.44 inches it is taller than some soft covers, so confirm the cover clears the underside of a raised tongue box or a generator housing.
Secure the top panel in your first week
The panel is the strength of the design and also its weakness. Before the first long drive, add a tie-down so the panel cannot lift. Owners report this single addition removes the wind problem entirely.
The other limitation is the loose-fitting profile. It is less tailored than a molded twin cover, so expect to see some daylight at the base. On a tank rack with gaps, that is worth checking against how much grit your route throws up.
6. SAMDEW 30 lb Nylon Cover – Turns a Tank Into a Table
SAMDEW 30 lb Propane Gas Tank Cover with Stable Tabletop Feature, Bag Only
Nylon cover with wooden top pad
12.8 x 12.8 x 23.2 inch
Drawstring closure
Four ventilation grommets
Pros
- Wooden top pad creates a stable tabletop surface
- Side flip flap and four grommets for hose and valve access
- Two side pockets hold hoses and accessories
- Side zipper plus drawstring hem gives a close fit
- Water and tear resistant nylon
Cons
- Soft bag gives almost no impact or puncture protection
- Sold as bag only with no rigid structure
- 23.2 inch height is tight on some taller fittings
This one solves a different problem. The wooden pad on top turns a covered 30 lb cylinder into a flat surface, which means a cup, a phone or a pan of water can sit on it while you work on the tongue. It is a small feature that turns a winter maintenance task into a bearable one.
Access is handled with a side flip flap and four ventilation grommets, so hooking a hose or checking a valve does not mean removing anything. A side zipper and a drawstring hem pull the nylon into a close, weather-shedding shape, and two outer flap pockets keep hoses and lighters off the ground.
It measures 12.8 inches square by 23.2 inches tall, and that height is the number to check carefully. It is snug on standard fittings and can be tight where an OPD valve or a taller regulator sticks up. Measure before you order, especially if your tanks carry a gauge or an aftermarket regulator.
It is a bag, not a shell. There is no rigid structure, so it does nothing against road debris, and in a high-wind plains location you should treat the drawstring hem as the only anchor point. Owners also place it in the mild-weather and storage category rather than the highway category.
Measure the height over your own valve
The 23.2 inch height assumes a standard cylinder collar and valve. If you have a tall regulator, a gauge, or a second-stage assembly, add that height to your measurement before you trust the fit. A cover that will not zip over your regulator is a cover that stays uninstalled.
For 20 lb cylinders this is not the right product at all, and for a dual-tank tongue you would need two. This is a single 30 lb bag designed around a specific use case.
Know that it will not survive a gravel road
Nylon resists water and tearing, not puncture. A stone kicked up under the cover, or a tongue box edge pressing into the bag, will mark the tank rather than the cover. If you drive rough routes, use this for storage between trips and keep a hard shell for the road.
The pocket and tabletop features also make it less suited to a crowded dual-tank rack, where you need to reach both valves quickly. One hand in a pocket is convenient, two cylinders deep in a rack is not.
7. ADCO 2713 Diamond Plated Vinyl Cover – Solid Value for 30-Lb Pairs
ADCO 2713 Silver Double 30 Diamond Plated Steel Vinyl Propane Tank Cover
Diamond-plated steel-look vinyl
Fits double 30lb tanks
Elasticized hem
Zipper access below the top
Pros
- Diamond-plated finish matches aluminum trailer skin
- Elasticized hem resists wind and follows the tank contour
- Zipper opens below the top to reach the valve
- Backed by a 3-year factory warranty
- Slim profile fits where a hard shell cannot
Cons
- Stitching is the weak point with failures inside a year
- Zipper has broken repeatedly for some owners
- No built-in hose exit flaps so owners cut their own
The ADCO 2713 solves a cosmetic problem well. The diamond-plated steel-look vinyl is designed to sit visually flush with an aluminium trailer skin, so on a polished trailer it disappears instead of looking like a bag strapped to the tongue. That is not a performance feature, but it is the reason many owners buy it.
It fits a double 30 lb pair and stays slim at 16 ounces, with an elasticized bottom hem that resists wind and follows the tank contour rather than ballooning around it. A zipper opening a few inches below the top gives you valve access without taking the whole cover off.
Durability is the trade. The stitching is the weak point and several owners report failure inside a year, and zipper failures recur often enough to plan around. The common workaround is to orient the zipper rearward so wind does not catch the pull, which costs nothing and helps.
What does set it apart from the other soft covers is the warranty. This one carries a 3-year factory warranty, which is the longest in this group and the strongest reason to choose it over a cheaper vinyl cover with no backstop. The rating spread is wide, with 63 percent five-star but 8 percent one-star, so inspect it early.
Orient the zipper and add your own hose flaps
Install the cover with the zipper facing rearward. Highway wind catches a forward-facing zipper pull, and the repeated failures in reviews trace back to that. A short length of hook and loop tape or a snap flap cut from the vinyl gives you a hose exit without fighting the zipper every time you connect a regulator.
Because the zipper runs one direction from the center, accessing a single tank is awkward by design. This cover is built for the pair, so plan to work on both cylinders at once.
Weigh the warranty against the stitching
A 3-year warranty is only useful if you keep the receipt and if the damage is a manufacturing defect rather than UV damage or a puncture. If your tanks live in full sun, check the vinyl every spring for chalking along the seams, because UV breakdown is not a warranty claim.
On a tongue with no room for a hard shell, the slim profile is the deciding factor. On an open trailer in a northern winter, buy a hard shell and accept the look.
8. Camco 40565 Single Polymer Cover – Straightforward Universal Fit
Camco RV 20-lb. Propane Tank Cover, Black
UV-stabilized polymer
Universal fit
20lb steel single tank
20.25 x 7.5 x 20.25 inch
Pros
- UV-stabilized polymer resists weather and road debris
- Easy access to gas and changeover valves
- Universal fit for 20lb steel single tanks
- Compact black finish suits most tank racks
Cons
- Single tank only so dual setups need two
- Capacity field is listed in gallons rather than pounds
- Simpler shell with less tailoring than molded twin covers
This is the no-fuss option. The Camco 40565 is a UV-stabilized polymer shell listed as a universal fit for 20 lb steel single tanks, with easy access to the gas valve and the changeover valve. Nothing about it is complicated, and on a basic trailer that is a feature.
It measures 20.25 by 7.5 by 20.25 inches, which is a compact footprint for a cover that still clears the valve hardware. The polymer is the same UV-resistant approach Camco uses on its heavier covers, so it holds up well to sun and weather for a static tank.
One thing to be careful about: the listing field for capacity reads 20 gallons rather than 20 pounds, which is a data error that can cause confusion when you are trying to confirm fit. The manufacturer part number is 40565, a 20 lb single tank cover, so verify against your actual cylinder collar and height.
It covers a single tank, so a dual setup means two covers. The review base of 320 is the smallest here, so treat the 4.4 average as encouraging rather than decisive. What owners do mention is a correctly sized, straightforward cover that does its job without fuss.
Confirm the pound rating, not the listing field
Before you order, put a tape measure on the cylinder rather than trusting the capacity field. You are checking the diameter across the collar and the height from the base to the top of the valve hardware. A 20 lb cylinder and a 30 lb cylinder are close enough in diameter that the number on the listing is the only thing separating them.
Because it is a universal fit, expect a slightly looser profile than a molded twin cover. On a tongue where the tank sits exposed to road spray, that gap is where water gets in.
Weigh simplicity against protection
Choose this cover if you want a set-and-forget solution with straightforward valve access and no assembly. Skip it if you drive gravel and dirt roads, since a simpler shell has less structure between your tank and whatever the road throws at it.
For storage-only use on a single-tank rig, it is genuinely good value. For anything more demanding, one of the molded dual shells will outlast it.
9. BougeRV Dual 20LB Oxford Cover – No Screws, One-Second Swap
BougeRV RV Trailer Propane Tank Cover, Visible Valve, Fit Dual 20LB Tanks
600D Oxford fabric
Waterproof
30 inch length fits two 20lb tanks
TUV valve window
Pros
- Clear TUV window shows the valve without opening the cover
- Bungee straps and snaps allow tool-free removal and refitting
- 600D Oxford fabric is waterproof and rust resistant
- Two cardboard top panels stop rainwater pooling
- Enlarged 30 inch length gives slack when snugged
Cons
- Soft body gives no hard-shell impact protection
- Must be matched carefully between 20lb and 30lb variants
- Hook and loop and bungee closures can flutter without a tie-down
The TUV window is the idea we liked most across all ten. A clear panel in the side of the cover lets you see the valve and the changeover position without opening anything, so you can confirm which tank is active at a glance in a snowstorm. That removes the single most common reason owners pull a cover off.
Everything else about the design is built around speed. There are no screws, just bungee straps and snaps, so removing and refitting the cover takes about a second. Two cardboard top panels keep the top flat and stop rainwater sitting in a pool on the cylinder collar, and the enlarged 30 inch length gives the fabric slack so it does not tear when you snug it down.
600D Oxford fabric is genuinely waterproof, which is more than most soft covers in this group claim. On a coastal rig with salt coming off the road, blocking water and slowing rust is the whole job, and this cover does that well for a fabric build.
The trade is impact protection. There is no hard structure between your tank and road debris, and the bungee and hook and loop closures can flutter at speed if you do not anchor them. Add a tie-down to the tongue frame before the first highway drive of the season.
Match the 20 lb and 30 lb variants carefully
This cover comes in two size options and picking the wrong one is the main reason it disappoints. A cover sized for 20 lb cylinders will sit loose on 30 lb tanks, and the bungee cords will not draw the fabric tight enough to shed water. Check the variant selector against your cylinder size before you add it to a cart.
The 30 inch length is what allows it to cover a pair of 20 lb tanks with room to adjust. Single-cylinder users should not expect this footprint to be neat, since the excess fabric has to go somewhere.
Anchor it before you drive with it on
Fabric covers that are only bungeed and snapped will lift and flutter, and repeated flapping shortens the life of the seams far faster than the weather does. A single strap to a tongue anchor or a ground stake solves it, and it is the first thing to do after installation.
If your route is paved and your winters are wet rather than windy, this is a very workable cover. If you run gravel and mountain passes, a hard shell is the safer long-term buy.
10. Camco 50514 Custom Molded Dual Cover – Tightest Molded Fit
Camco Dual Camper Propane Tank Cover, Custom Molded, 30 lb, Black, 50514
Custom molded UV-protected polymer
Fits two 30lb tanks
29.5 x 15.5 x 26.25 inch
Hinged top panel
Pros
- Custom-molded polymer feels sturdier than factory RV covers
- Hinged top panel checks valves without removing the cover
- Precise fit over two 30lb steel tanks
- Weather-resistant build handles road debris
- Two halves bolt together simply
Cons
- Highest price in this group and arrives in two halves
- Assembly needs a socket and screwdriver that are not included
- Front to back bolt layout means sliding the cover down to fasten
- Top panel can feel loose and lift in strong wind
Fit is the reason to spend more here. The Camco 50514 is custom molded rather than a universal shell, and it measures 29.5 inches wide by 15.5 inches deep by 26.25 inches tall around a pair of 30 lb steel tanks. Multiple owners report the fit is precise, which is the thing you notice every time you walk past the trailer.
The build is heavy-duty UV-protected polymer and owners consistently call it sturdier than the covers that came from the factory with the RV. The hinged top panel checks the gas and changeover valves without removing the whole shell, and the two halves bolt together simply, including on a tailgate if that is how you work.
There are real logistics to consider. The cover arrives in two halves, and assembly needs a socket and a Phillips screwdriver that are not included. Because the bolts run front to back, you have to slide the assembled shell down onto the tanks to finish fastening, so you need someone to hold it or a place to build it first.
It is the most expensive cover in this group, and the review base of 218 is the smallest, so the 4.6 average comes from a smaller pool. What that pool agrees on is build quality and exact fit, with the top panel tension as the main minor complaint.
Plan the assembly before the tanks go on
Because the bolts run front to back, you cannot finish the cover lying on the ground. Build it, check the fit empty, and only then place it over your tanks, ideally with a second person. Have a socket and a Phillips screwdriver ready, since neither is in the box.
Measure your clearance first. At 26.25 inches tall and 15.5 inches deep it is the tallest and deepest cover here, and it will not fit under a low tongue box or beside a large jack assembly.
Check the top panel tension on the first warm day
The snap-fit hinged panel can feel loose, and a loose panel that lifts in strong wind defeats the purpose. Test it in the first week, and if it moves, add a small latch or a short strap across it.
If you want the tightest, most OEM-looking fit and you have the space on your tongue, this is the cover to buy. If your rig is tight or your budget is fixed, the Flame King dual 30 lb shell gets you most of the way there.
How to Choose an RV Propane Tank Cover That Survives Winter
Material decides everything. A hard molded shell, usually polypropylene, blocks rain, UV and impact and stays rigid in cold. A soft vinyl cover is lighter, cheaper and slimmer, but the seams and zippers are the parts that fail first, and cold stiffens the material. A fabric cover in Oxford or nylon is the lightest and often the most waterproof in waterproof terms, but it offers nothing against impact. A metal or DIY enclosure is the only real answer for a horizontal ASME tank, and it must have vent holes.
Fit decides whether you will actually use it. Measure the diameter across your cylinder collar, the height from base to the top of the valve hardware, and the width of your tank pair. Then measure your tongue: jack clearance, the height under a raised box, and the gap beside a chain support and a 7-pin connector. A cover that fouls your tongue hardware will sit crooked and wear at the seam.
Valve access decides whether it suits cold-weather living. If you run appliances between October and March, you want a removable top panel, a flip flap, a clear window or real access ports. If the RV is dormant, access matters much less and you can optimise for impact protection instead.
Climate decides how tough you need it to be. In northern snow country with freezing temperatures and road grit, a hard molded shell is the right default. On coastal routes with salt spray, water exclusion matters most, so a well-sealed vinyl or a waterproof Oxford cover works. In desert sun, UV resistance dominates and light colours with UV protection outlast dark vinyl. On open plains with serious wind, treat the anchor system as part of the product, because a cover that lifts is a cover that ends up in a ditch.
One honest warning about the whole category: every soft cover on this list will eventually fail, and it will usually fail in the stitching or the zipper before the fabric gives up. Inspect seams each spring. If the fabric is still flexible and the thread is not broken, clean it and put it back on. If it has gone chalky, stiff or split, replace it rather than hoping.
And know what a cover does not fix. It does not stop a regulator or a supply line from freezing, which is a cabinet problem solved by skirting, heat tape and open cabinet doors. It does not stop a 30 lb tank from running out quickly, since a full cylinder burns through in roughly two and a half days once temperatures sit at or below freezing. And it does not winterise the rest of your RV, as owners on RV forums report every season with covered trailers that still develop propane leaks and dry-rotted tires.
Worth thinking about if you camp in genuinely cold conditions, or just to understand why cold weather makes you hungrier. Our piece on why nails grow slower in winter covers the same biology from a different angle, and proper layering makes a real difference in how cold you actually feel.
Propane Cover Safety: Venting, Valves and Regulators
Propane is heavier than air. That single fact drives every safety rule about propane tank covers, and it is the most repeated truth on RV owner forums. Any propane that escapes settles low instead of rising away, so a cover must never create a sealed pocket around a cylinder with gas in it. If you build an enclosure yourself, drill vent holes near the bottom. Never cover a propane tank while performing a leak check.
Keep the OPD valve, the regulator and the changeover valve reachable while the cover is installed. This is why the Flame King, Camco and BougeRV options in this list all provide some form of access. If your cover has no access of any kind, plan to remove it before you touch a valve, and accept that you will be doing that in the cold.
Never fit a cover over a tank that is being filled, serviced or leak checked, and never trap a cylinder inside a cover while an appliance is running and a leak is suspected. If you smell propane, do not troubleshoot under a cover. Shut the appliance, close the tank valve, open the cabinet and get away from the RV.
For horizontal ASME tanks, where purpose-built covers barely exist, a repaint can be the better long-term answer, and re-certification is usually far cheaper than replacement. One owner in British Columbia described recertification with a new valve costing several times what the same work cost him in the United States, where owners report a visual-only check as a quick counter visit and a full pressure check as a modest, routine job with certification good for several years. Costs vary widely by jurisdiction, so confirm locally before you book anything.
That same owner repainted in 2018 and reported the corrosion had not returned. Another owner in the same thread prefers an enclosure over painting precisely because ordinary paint fails within a year or two. Both are reasonable, and the explanation for the failure is physical: a tank expands and contracts with temperature and with cycling from empty to full, so ordinary paint cannot stay adhered. If you mask a label before painting, one forum tip is to use Vaseline rather than tape, which avoids marring the decal.
For most owners, though, the propane question is simpler than any of this. If your tanks already have surface rust, a cover slows the damage but does not reverse it. Sanding and treating the corrosion, then covering, beats covering a rusted tank and hoping.
Frequently Asked Questions
Should I cover my propane tank in the winter?
Yes, in most climates. A cover keeps rain, snow and UV off the tank, which is what actually causes corrosion, and adds insulation that slows temperature swings. It will not stop a tank from going cold in extreme cold, and you must keep the valve and regulator accessible. Never cover a propane tank while performing a leak check.
What is the best cover for propane tanks on a camper?
For most campers, a molded hard shell over the correct tank size is the best answer. The Flame King dual 30 lb shell suits standard RV setups, the Flame King dual 20 lb version fits smaller tanks, and the BroilPro vinyl cover is the proven single-tank option if you run one 20 lb cylinder.
What are the best propane tank covers?
The ten covers in this roundup break down by use. Hard molded shells such as the Flame King dual 30 lb and the Camco 50514 handle impact and cold best. Soft vinyl covers such as the ADCO 2113 and ADCO 2713 fit tight tongues. Fabric covers such as the BougeRV Oxford and the SAMDEW nylon bag are lightest and fastest to refit.
Do propane tank covers blow away in the wind?
They can. Fabric covers held only by bungee cords or hook and loop closures will lift and flutter at highway speed, and loose top panels on hard covers can lift too. Anchor any cover to the tongue frame or a ground stake, and on open plains or mountain passes treat the anchor as part of the product.
Will a propane tank cover keep the tank from freezing?
No. A cover blocks rain and sun and adds a thin layer of insulation, but it does not generate heat. Regulators and supply lines freezing is a cabinet problem, handled with skirting, heat tape and open cabinet doors. Filling your tanks before a cold snap also helps, because an empty cylinder has nothing left to deliver as pressure drops.
Why is my propane tank covered in frost?
A cold tank pulls moisture from the air, and that moisture condenses and freezes on the colder surface, which is the cylinder wall. This happens under a cover and without one. A cover can slow how fast the tank loses heat, but it cannot prevent condensation on a tank sitting at or below freezing.
Is it better to cover an RV in the winter or not?
It depends on your climate and your tanks. Covering slows rust in wet and salty conditions and protects paint from UV. Bringing cylinders indoors is better where horizontals are expensive to replace, and repainting a sandblasted tank with a proper propane paint can outlast a cover. No forum has a universal answer, and owners genuinely disagree.
What uses the most propane in an RV?
Heating dominates in cold weather, and a full 30 lb cylinder burns through in roughly two and a half days once temperatures sit at or below freezing. Covering the tank does not change that rate. The practical fix is to plan refills around cold snaps rather than to expect a cover to extend your range.
The Verdict for Winter RV Propane Storage
The best RV propane tank covers for winter come down to two questions. How hard is your winter, and how many tanks are on your tongue? Heavy snow, freezing temperatures and grit-heavy roads point to a molded hard shell in the right size. Mild winters, tight tongues and quick valve checks point to vinyl or fabric, where the lighter build and the access features matter more than impact resistance.
Our first pick, the BroilPro heavy-duty vinyl cover, is the most proven thing in this group with a 4.7 average across more than 4,200 reviews, and it is the right answer for a single 20 lb cylinder on a paved-route rig. The Flame King dual 30 lb hard shell is what we would put on a full-size trailer that sees real winters, and the Camco 50514 is the one to buy when exact molded fit matters more than cost.
Whatever you choose, anchor it, keep the valve reachable, and remember what it is for. A cover slows corrosion and blocks sun. It does not stop a regulator freezing, and it is not a substitute for winterising the rest of your rig. Get the propane side right first, then pick up a proper cold-weather kit for the humans, including one of the best winter coats for men we tested if you are heading north this season.
