Three covers sized for 40-foot travel trailers compared by length range, fabric layers, wind straps and vents, for owners of the longest towable rigs.

By Hardcastle's RV Editors

10 min read3 products evaluated

Travel trailer covers sized to a full 40 feet are rare, because most brands stop at 38 feet and jump to fifth-wheel patterns after that. This short list includes only travel trailer covers whose listings state a range topping out at 40 ft, ranked on fabric, wind strapping and ventilation. A fifth-wheel cover is not a substitute, since the front cap shape does not match a conventional trailer.

How We Built This Shortlist

Each pick was assessed across 4 criteria weighted for real-world use.

Size range
We included only travel trailer covers with a stated range that reaches 40 feet.
Fabric
We compared 9-layer and 7-layer builds and UV claims.
Wind system
We counted straps and noted tension panels and belly straps.
Kit and access
We noted tire covers, vents and zippered panels.

What Matters Before You Choose a 40 Foot Travel Trailer Cover

Key buying criteria so you get the right fit the first time.

  1. Range reaching 40 ft

    A cover sold for 37-40 or 38-40 feet matches the longest travel trailers. Overall length includes the tongue and rear ladder, so a 36 ft body may need a 40 ft cover. Measure end to end and look for a range with your number near the top.

  2. Travel trailer vs fifth wheel

    Fifth-wheel covers include a front cap shaped for the overhang, so they do not drape correctly on a conventional trailer. Using the wrong style leaves gaps. Check the title says travel trailer.

  3. Fabric layers

    Nine-layer fabric adds tear and water resistance, and seven layers is lighter and cheaper. Longer covers face more stress at the seams. Look for the layer count in the title or description.

  4. Wind control

    A 40 ft cover catches more wind, so long straps and tension panels matter. Belly straps and extra-long windbreak straps keep the hem down. Count straps and look for tension panels.

  5. Cover weight

    Large covers can weigh enough to need two people. Lighter fabric reduces strain at install. Check for a weight reduction claim or a pound weight in the listing.

Before You Bring One Home

Can I use a fifth-wheel cover on a travel trailer?

It is not designed for it. Fifth-wheel covers include a front cap, so choose a travel trailer cover like RVMasking 37-40.

How do I measure for a 40 ft cover?

Measure from the rear bumper to the tip of the tongue, including the ladder. Match the range, leaving some slack.

Are 7-layer covers enough?

For seasonal use they can be. The YITAHOME adds tension panels, while 9-layer covers resist tearing better over years.

How do I keep a large cover from billowing?

Use all bottom straps and belly or windbreak straps. The RVMasking has a horizontal strap, and the YITAHOME has two extra-long straps.
