The best Class A RV cover for most 40-foot motorhomes is the MOFEEZ Class A RV Cover 37-40ft, because its 9-layer waterproof top, 8 vents and 3 roll-up zipper panels cover the jobs a big rig needs. Pick the RVMasking if your coach sits in an exposed, windy spot, or an Oxford fabric cover if lifting a thick non-woven cover onto a tall roof is the harder part for you.
A 40-foot Class A is a big, boxy target for sun, rain and snow. The right cover has to fit the length first, then keep water out while letting trapped moisture escape.

How we picked the best Class A RV covers for 40-foot motorhomes
We ranked these covers by fit range for a 40-foot coach, top fabric and water resistance, then by the straps and vents that decide how well a cover stays put. Every pick here lists a length range that covers 40 feet or comes close, so the first job is checking which size band your motorhome falls into.
The short answer on sizing: measure your coach bumper to bumper, including the ladder and spare tire, then buy the size whose range contains that number. A 40-foot coach can land in a 37-40 ft band or a 40-43 ft band, and the wrong band either strains at the seams or leaves slack that flaps in wind.
Top fabric and water resistance
The top panel does most of the work against rain and UV. Five of the seven picks here use a 9-layer non-woven top, which is thick, tear-resistant and carries a waterproof membrane.
FRUNO and SELIMON go the other way with 300D Oxford cloth: lighter, easier to lift, and coated with PU to shed water.
Non-woven fabric ages faster under strong sun unless it has UV inhibitors mixed in. DenForste states the highest UV blocking figures here at 98.5% UV-A and 99.8% UV-B.
MOFEEZ, RVMasking and Umbrauto all add UV-resistant composites to their top layers.
Water resistance matters most in wet climates. MOFEEZ, RVMasking, Umbrauto, FRUNO, DenForste and SELIMON all state a waterproof level.
Leader Accessories is water repellent rather than waterproof, so it suits a drier climate or a covered storage spot.
Wind straps and fit
Wind is what destroys most covers. A cover that billows pulls at seams and corners until it tears.
Look for a long strap that wraps under the coach, corner patches at the high-stress points, and a tension system front and back.
RVMasking leads here with an extra-long horizontal strap plus roof straps, bottom windproof straps and reinforced patches on 8 corners. MOFEEZ uses 6 adjustable side straps and 2 wrap-around straps.
Umbrauto adds 7 wind ropes and 3 extra windproof straps on top of its bottom fixing straps.
Elastic hems help too. RVMasking, FRUNO and Leader Accessories all use an elastic hem to pull the fabric close to the body.
If your coach sits in an open lot, weight the strap count more heavily than the fabric thickness.
Vents and access panels
A cover that traps moisture causes more damage than it prevents. Vents let air move and release humidity, and zippered panels let you check the interior or reach the door without pulling the whole cover.
Most picks here include vents and at least 3 zippered or roll-up panels. MOFEEZ, RVMasking, Umbrauto, Leader Accessories and SELIMON each list 3 or 4 access points.
That matters on a 40-foot coach, where you'll want to open the door and peek inside during storage.
If you plan to run the fridge or check on the interior through winter, choose a cover with roll-up panels that stay open. For a closer look at which fabrics handle rain best, read are RV covers waterproof.

The best Class A RV covers for 40-foot motorhomes
Each cover here earns its place for a different reason, from the most complete kit to the lightest fabric. Read the badge first to match your storage situation, then the details.
MOFEEZ Class A RV Cover 37-40ft: Best overall
- 9-layer non-woven top
- 8 vents
- 3 roll-up zipper panels
- Tire covers and gutter covers included
The most complete kit here for a 40-foot rig, with a thick waterproof top and easy side access.
Pros
- 9-layer top with waterproof membrane
- 8 vents and 3 roll-up zipper panels
- Tire covers, gutter covers and repair patches included
Cons
- Runs to 40 ft only, so measure carefully
- Thick fabric is heavier to lift on a tall roof
MOFEEZ earns the top score because it covers every base for a 40-foot coach. The top is 9 layers of non-woven fabric with UV-resistant composites and a waterproof membrane, and the sides are 3 layers thick.
That gives you a heavier cover than the Oxford options, with more protection against sun aging and tearing.
Wind control comes from 6 adjustable side straps with buckles and 2 wrap-around straps. Eight vents reduce wind pressure and release moisture, while 4 reflective strips front and back make the coach easier to see at night.
The kit is the most complete here: tire covers, gutter covers with sponge design, 2 reinforced straps, repair patches, a storage bag and a toss bag. Three rollable zipper panels on the passenger side let you step in or check the interior without pulling the cover.
The trade-off is weight. A 9-layer top is heavier to lift onto a tall Class A roof, and this size runs to 40 feet only, so a coach sitting right at the limit needs careful measuring.
Best Class C RV covers for winter follows the same sizing logic if you're covering a smaller coach.
RVMasking Class A RV Cover: Best for windy storage
- Extra-long horizontal strap
- 9-layer non-woven top
- 3 zippered roll-up panels
- 8 vents
Built around wind control, with a long belly strap and reinforced corner patches on a genuine 9-layer top.
Pros
- Long horizontal strap wraps the bottom
- Reinforced patches on 8 corners
- 4 tire covers and 6 gutter covers included
Cons
- Smallest size starts above 38 ft
- One-year manufacturer warranty
RVMasking is the pick when your coach sits where wind hits hard. Its extra-long horizontal strap wraps around the bottom to stop wind getting under the fabric and billowing it.
Roof straps, bottom windproof straps, panel straps and an elastic hem all pull the cover close to the body.
The top is genuine 9-layer non-woven fabric with a 4% anti-UV composite. An outer water-repellent coating makes rain bead up and roll off, and a breathable middle membrane lets moisture out on sunny days.
The 8 vents and 3 zippered roll-up panels match the rest of the field.
RVMasking reinforces all 8 bottom corners with longer patches and raises the rear corner patches to protect against ladder edges. The kit adds 4 tire covers, 6 gutter covers, 2 weighted toss sticks, a repair patch and a storage bag.
The fit range starts at 38 ft 1 in, so a coach under that needs a different cover. The manufacturer warranty is 1 year, shorter than Umbrauto's 3-year term.
Read can an RV cover fit over slide-outs before you order if your coach has wide slides.
Umbrauto Class A RV Cover 37' ~: Best for access panels
- 4 zippered panels
- 6 vents
- 7 wind ropes and 3 extra windproof straps
- Ladder cover included
A vent-heavy cover with four zipper panels and a long accessory list, backed by a three-year warranty.
Pros
- 4 zippered panels for doors and engine bay
- 3-year warranty
- Ladder cover and weighted toss bag included
Cons
- Side fabric is non-woven rather than Oxford
- Extra straps take time to set up
Umbrauto suits owners who want the easiest access. Four zippered panels reach the doors and engine area, and the kit includes a weighted toss bag so you can thread straps without crawling under the coach.
The top is a 9-layer sun-resistant composite fabric with a built-in waterproof membrane.
The wind kit is generous: 4 adjustable bottom straps, 7 wind ropes and 3 extra windproof straps. Six vents reduce pressure and release moisture.
Reflective strips front and rear help with night visibility.
Umbrauto backs the cover with a 3-year warranty, the longest here. The kit also adds a ladder cover, 6 gutter covers with sponge design and a repair patch.
Side panels use heavy-duty non-woven fabric with UV additives rather than Oxford cloth.
The trade-off is setup time. More straps mean more work each time you fit the cover, so it suits a coach that stays covered for long stretches rather than one you uncover often.
What is the best material for an RV cover explains why the side fabric matters as much as the top.
FRUNO Oxford Fabric Class A RV Cover: Best for winter snow
- 300D Oxford top
- PU coating
- Rated from -4 F to 120 F
- 3 rollable access panels
A lighter Oxford cloth cover that handles cold snaps and wet snow without the bulk of a thick non-woven top.
Pros
- 300D Oxford top with PU coating
- Cold rating down to -4 F
- 2-year support with no return needed
Cons
- Middle-fixed straps sit lower on the body
- Sizing starts at 40 ft
FRUNO is the cover to choose when winter is the main threat. The top is 300D Oxford fabric over 150D sides, with a dense PU coating and UV inhibitors.
FRUNO rates the cover from -4 F to 120 F, so it holds up through a hard cold snap without the bulk of thick non-woven fabric.
The straps fix to the middle of the sides rather than the bottom, which pulls the cover closer to the body. An elastic hem, front and rear panel straps and 2 lashing straps add more hold.
Three rollable panels open for access to the trailer.
FRUNO includes 4 tire covers, 6 gutter spout covers, 2 repair patches and a storage bag. The kit also carries a 2-year support term with a repair or replacement offer, and FRUNO says no return of the original item is needed.
Sizing starts at 40 ft and runs to 43 ft, so a coach just under 40 ft needs a smaller size. The lighter Oxford fabric is easier to lift but offers less padding than a thick non-woven top.
Our material for RV cover guide compares Oxford and non-woven in more depth.
DenForste RV Cover for 40'-43' Class: Best for UV protection
- 9-layer non-woven fabric
- 98.5% UV-A and 99.8% UV-B blocking
- 8 vents
- 3000mm waterproof rating
The strongest UV claim here, with a 3000mm waterproof rating and a roll-up zipper door.
Pros
- High UV blocking figures
- 3000mm waterproof rating
- Gutter covers with sponge design
Cons
- Thick non-woven top is heavier
- Vent count is no higher than MOFEEZ and RVMasking
DenForste fits buyers who park in strong sun. It states blocking of 98.5% of UV-A and 99.8% of UV-B rays, the highest figures here, and the top is 9 layers of non-woven fabric with reinforced edges and corners.
That combination slows paint fade and fabric aging.
Water protection is rated to 3000mm, and the cover uses extra-long windproof straps, front and rear straps and side buckle straps. Eight air vents handle moisture and pressure.
Four reflective strips front and rear aid night visibility.
A roll-up zipper door gives access without removing the cover, and gutter covers with sponge design wrap sharp spouts. A toss bag lets you fit straps without crawling underneath.
The vent count is no higher than MOFEEZ and RVMasking, and the thick non-woven top is heavier to handle. Sizing runs 40-43 ft.
If UV is your main concern, this is the strongest stated figure in the group.
Leader Accessories Class A RV Cover: Best for one-person setup
- Weighted-buckle toss bag
- 9-layer top
- 6 vents
- 4 rollable zippered panels
A budget-friendly cover with a toss bag that speeds up strap threading when you work alone.
Pros
- Toss bag for solo installs
- 4 rollable zippered panels
- Ladder cover and long straps included
Cons
- Water repellent rather than waterproof
- Lower UV blocking than the leaders
Leader Accessories suits the owner who installs alone. A weighted-buckle toss bag lets one person fit the straps in about 30 minutes without extra tools.
The top is 9-layer non-woven fabric with a waterproof membrane and high-density UV coating.
The wind system includes front and rear tension panels, 4 elastic corner hems, 2 extra-long all-around straps, 4 bottom straps and locking buckles. Six vents keep air moving.
Four rollable zippered panels reach the doors and engine bay, and reflective strips front and rear help at night.
The kit adds a toss bag, ladder cover, 2 reinforced long straps, a repair patch, a gutter protector and a storage bag. The cover fits 40-42 ft.
The main trade-off is water resistance. Leader Accessories rates the cover water repellent rather than waterproof, so it sheds rain but won't hold up to sustained heavy weather like the leaders.
It also states lower UV blocking than DenForste. Are RV covers waterproof helps you weigh that difference.
SELIMON 300D Top Class A RV Cover: Best for easy lifting
- 300D Oxford top
- 15 adjustable straps
- 8 top vents
- 3 roll-up zippered doors
A white Oxford cloth cover that weighs less than non-woven rivals, so it is easier to lift onto a tall Class A roof.
Pros
- Lighter Oxford fabric
- 15 built-in straps and 2 wraparound straps
- 3 roll-up zippered doors
Cons
- White fabric shows dirt faster
- No ladder cover in the kit
SELIMON is the lightest cover to handle. The top is 300D Oxford fabric and the sides are 150D, which makes the whole cover lighter than a 9-layer non-woven rival.
SELIMON says the fabric offers better waterproofing and tensile strength than non-woven, and the anti-UV component blocks more than 98% of UV rays.
Wind control comes from 15 built-in adjustable straps and 2 extended wraparound straps. Eight top vents reduce wind stress and release humidity.
Three roll-up zippered doors reach the entry points and stay open at the roofline.
The kit includes 4 tire covers, 2 webbing straps, 6 gutter spout covers, 2 repair patches and a storage bag. SELIMON offers 2-year support with repair patches for minor damage and a replacement if damage exceeds what a patch can fix.
The white fabric shows dirt faster than the grey covers here, and there's no ladder cover in the kit. Sizing runs 40-43 ft.
Choose it if lifting a heavy cover onto the roof is the part you dread.
Sizing and fitting a cover on a 40-foot Class A
Buy by measured length, not by the coach's model name. A 40-foot motorhome that's 40 ft 4 in with the ladder and spare tire needs the next size up in any band that stops at 40 ft.
Measure the full length bumper to bumper, including the ladder and spare tire. Leave the hitch out.
Then measure width with the slides in the position you store the coach. Most covers here list width and height too, so compare those against your coach before ordering.
Round up when you sit near the top of a range. A cover that's too tight strains at the seams and zippers.
A cover that's too long gathers slack that flaps in wind, so aim for the size band your measured length falls in with a little room.
Height matters as much as length. The MOFEEZ size lists 492 x 110 x 120 inches for its 37-40 ft band, so compare the height figure against your coach's roofline plus any roof accessories.
If your coach carries a big roof AC unit or satellite dish, the extra height needs room.
Check the fit over slide-outs. Measure width with the slides out if you store the coach that way, or confirm the cover's width leaves room for the extra inches.
Our RV cover with slide out guide walks through that measurement.
Installing and caring for a Class A RV cover
Fit the cover on a calm day. Wind turns a large cover into a sail and makes the strap work harder than it needs to be.
Two people make a 40-foot cover much easier to handle, even with a toss bag.
Pad sharp edges first. Gutter spouts, ladder rungs and antenna mounts all cut fabric over time.
Most kits here include gutter covers with sponge design, so slide those on before the cover goes up. FRUNO and SELIMON both suggest wrapping sharp edges with towels or foam pads.
Thread the straps and snug them down, but don't over-tighten. A cover needs a little room to sit over the roof accessories and let the vents work.
Work from front to back, then check the corners last, since those take the most wind stress.
Check the cover after storms. A loose strap or a flap that's started to tear is easier to fix with a repair patch than to replace.
All seven picks include adhesive repair patches or offer replacement support.
Clean the cover each season. A soft brush and mild soap remove bird droppings and dust that hold moisture against the fabric.
Let it dry fully before folding, and store it in the included bag away from sharp tools.
Store with the vents clear. A cover folded against a wall or under a tarp can trap moisture.

Which Class A RV cover should you buy for a 40-foot motorhome?
Buy the MOFEEZ 37-40ft if you want the most complete kit and your coach measures 40 feet or less. Pick the RVMasking if your coach sits in an exposed, windy spot and the size band fits.
Choose FRUNO or SELIMON if lifting a thick non-woven cover onto the roof is the hard part.
For strong sun, DenForste states the highest UV blocking here. For easiest solo access, Umbrauto and Leader Accessories both include a toss bag and multiple zipper panels.
Leader Accessories is the budget pick, though its water repellent rating suits a drier climate better than a wet one.
Check your measured length first, then match the fabric to your weather. If you store through a wet winter and want to know how each fabric handles rain, read are RV covers waterproof and what is the best material for an RV cover.

Frequently asked questions
Are Class A RV covers waterproof?
Many Class A covers use a waterproof membrane or PU coating on the top panel, while the sides stay breathable to let moisture escape. Check the water resistance level before you buy, since water repellent fabric sheds rain but is not the same as waterproof.
Will an RV cover fit over slide-outs?
Yes, when the cover's width accounts for the slide-outs in their extended or retracted position. Measure with the slides in the position you store the coach, and choose a cover whose width leaves room for the extra inches.
Do I need to cover the tires and gutters too?
Tire covers and gutter covers come in most kits here, and both are worth using. Gutter spouts can tear fabric, so slide the sponge covers over sharp edges first, and fit the tire covers to block UV damage to the rubber.
How long should a Class A RV cover last?
Lifespan depends on fabric type and sun exposure. Non-woven covers with a 9-layer top and UV inhibitors usually hold up longer in strong sun, while Oxford cloth is lighter and easier to handle.
Replace a cover once the membrane tears or the fabric turns brittle.
