Camco ULTRAGuard 36-38-Ft Class A RV Cover with Zipper Entry Doors and Covered Air Vents, Spunbond Polypropylene, Includes Storage Bag (45735) Review (2026)

Who this cover suits

This cover is built for owners of 36 to 38 foot Class A motorhomes who store their rig outdoors, whether in a driveway, storage lot or seasonal parking spot, and want protection without the cost of a rigid carport or building. It suits owners who plan to access the coach occasionally during storage, since the zipper entry doors mean you can check on the interior or grab something from a bay without pulling the whole cover off and refitting it afterward. Anyone storing a smaller Class A should look at Camco's shorter-length ULTRAGuard versions instead, since this specific size is cut for the 36 to 38 foot range and will not cinch down properly on a shorter coach.

Specs explained in plain English

The top of the cover is built from three layers: two outer plies of spunbond polypropylene sandwiching an inner microporous breathable film, while the sides use two layers of spunbond polypropylene. That breathable layer is what lets moisture vapor escape from inside the cover rather than getting trapped against the paint, which is also the job of the covered air vents built into the design. Those vents are covered specifically to stop wind from billowing under the cover while still letting air move through. The cover ships with a storage bag so it can be folded down to a manageable size when the coach is on the road instead of in storage.

Living with it day to day

Getting the cover on and cinched is realistically a two-person job at 36 to 38 feet, given the size and weight of the material involved, and most owners find it easier to fit on a calm day rather than fighting wind while draping the top layer. Front and rear cinching straps along with an underbelly strap system are built in to pull the cover into a closer, more custom fit once it is in place, which helps keep it from flapping loose in storage. The zipper entry doors are the main convenience feature for day-to-day access, letting you get inside to check on the rig without undoing the straps and pulling the cover back.

Where it falls short and how it compares

Against rivals like the VINPATIO cover, which uses a 7-layer top, or the Leader Accessories covers with a 5-layer top, the ULTRAGuard's 3-layer top and 2-layer sides are lighter duty, which is likely why those thicker rivals edge it out slightly in this guide's ranking despite this cover's useful zipper doors and covered vents. The trade-off is reasonable for owners in milder storage climates or shorter-term outdoor storage, but anyone expecting heavy snow load or storing the coach outdoors year-round in a harsh climate may get more durability from a thicker-layer competitor even at a similar size fit.

Verdict and who should pick something else

For a 36 to 38 foot Class A owner who wants easier access during storage and solid moisture control from the covered vents and breathable top layer, this cover is a sound pick, especially with the storage bag included for the off season. Owners in harsher climates or those who want the added durability of a thicker multi-layer top should compare it against the VINPATIO or Leader Accessories covers in this guide, which use more plies on top. Double check the 36 to 38 foot fit against your exact coach length before ordering, since an oversized or undersized cover will not cinch down properly regardless of how many layers it has.
