Measure the rig you own — any type — not the model name on the box.
Research — sizing, materials, and fit features from manufacturer listings and published owner guidance. The one personal fact behind this page: the site's owner put the cover on his Four Winds motorhome on October 25, 2026, ahead of winter in Utah.
This page covers how to pick a cover that fits your rig — Class A, Class B, Class C, travel trailer, or fifth wheel — and survives a winter: measuring, materials, fit features, and what to do before it goes on.
Cover sizes are sold by length ranges, and the wrong range is the most common cover mistake. Measure bumper to bumper — coupler to bumper on a travel trailer — and include anything that sticks out: the spare tire, the ladder, and any rear storage. Then check the manufacturer's size chart against your measurement — don't trust a model-year listing alone, because the same model name can span different lengths.
Also check height and width against the cover's stated fit — length is only half the sizing question, and height is where tall rigs get caught out. Typical heights including the roof air conditioner: Class B around 9–10 feet; Class C around 10–11 feet; travel trailers around 10–11 feet; Class A and fifth wheels around 12–13 feet. A cover that fits the length but not the roof height will strain at the AC shroud and tear at the seams, so check the cover's height limit as well as its length band.
Size bands vary by maker — always check the specific cover's chart — but covers are commonly sold in bands like these. Find your type, then match your measured length to a band. (One example: the owner's Four Winds Class C was sized by measured length, not by model name — the same rule applies to every type below.)
| RV type | Typical length range | Typical cover band to look for | Height to check |
|---|---|---|---|
| Class B camper van | ~17–24 ft | 17–20, 20–23, or 22–24 ft bands | ~9–10 ft |
| Class C motorhome | ~20–35 ft | 20–23, 24–27, 28–31, or 32–35 ft bands | ~10–11 ft incl. roof AC |
| Class A motorhome | ~25–45 ft | Bands in 2–4 ft steps, up to 40+ ft | ~12–13 ft — check the cover's height limit |
| Travel trailer | ~12–35 ft (including tongue) | Bands from ~14 ft up, by length | ~10–11 ft |
| Fifth wheel | ~25–45 ft (trailer body) | Bands by body length | ~12–13 ft — tallest; check the cover's height limit |
If your measurement falls on a boundary between two bands, the usual guidance is to size up: a slightly loose cover can be cinched down with straps, but a too-short cover won't reach the bottom and will ride up in wind. Too much extra length, though, leaves fabric flapping — which abrades the finish — so don't jump two bands.
| Material | What it is | Trade-offs |
|---|---|---|
| Multi-layer polypropylene | The common cover material. Layers add water resistance and durability; the top layer handles UV and weather, inner layers stay softer against the rig's finish. | Good all-around value. Quality varies a lot by layer count and weight — compare fabric weight, not just layer claims. |
| Polyester | A tougher, often heavier fabric, sometimes with a waterproof coating. | More durable and more abrasion-resistant, but can be less breathable unless vented. Heavier to handle on install day. |
| Premium / spunbond composites | Higher-end fabrics (including Tyvek-type materials) marketed for maximum breathability plus water resistance. | Best breathability-to-protection balance, at a higher price. Worth it if the rig sits through wet winters. |
Wash the rig first, let it dry, and make sure nothing sharp is left sticking out that could wear through the cover in wind. Put the cover on on a calm day if you can — wrestling a big cover in wind is a two-person job at best. Fold down or pad anything that pokes: antennas, sharp gutter ends, and mirror arms are the usual tear points. If your cover has a stuff sack, keep it — a cover stored loose in a bay gets dirty and torn before next winter.
Specific covers, sizes, and prices are not filled in yet — they will be added only after checking current manufacturer specs and retailer listings, not from memory.
Buy by your measured length, not by the model name on the box. Prioritize breathability and a secure fit over the cheapest price — a cover that blows loose or traps moisture does more harm than no cover at all. And whatever you buy, wash the rig before it goes on.
Can I just use a tarp instead of an RV cover?
A tarp is the classic false economy. Tarps don't breathe, so moisture condenses underneath and grows mildew; they have no soft lining, so they abrade the finish in wind; and they have no shaped fit, so they billow and tear. A proper RV cover costs more for real reasons.
Should the cover reach the ground?
No. A cover should end just below the rig's sides. Fabric on the ground wicks moisture and dirt, and gives mice easy access. If your cover pools on the ground, it's too long.
Do I need tire covers if I have a full RV cover?
Usually yes — most full covers leave the tires exposed, and UV ages rubber all winter. Tire covers are cheap and they protect the one part of the rig that touches the road.
How long should a cover last?
It depends on material, sun exposure, and storms — a well-made cover commonly lasts several seasons, a cheap one sometimes a single winter. UV brittleness, torn straps, and thinning at stress points are the signs it's done. When the fabric goes brittle, replace it: a failing cover abrades the rig.
Can I put the cover on alone?
On a smaller rig — a Class B or a short travel trailer — yes, on a calm day, working from the roof down with the cover unrolled carefully. On a larger rig — a Class A, a long fifth wheel, or a long Class C — or on any windy day, it's a two-person job — one on the roof feeding the cover down, one on the ground guiding it. Rushing it alone in wind is how covers tear and people fall.
