RV Cover for 18ft - 20ft Travel Trailer - Heavy-Duty 6-Layer

In this review the RVGUARD RV Cover for 18' - 20' travel trailers is evaluated for owners who store trailers outdoors and want durable, weather-resistant protection. The bottom line: this cover is best for owners who need a breathable, waterproof fabric and extra features like vents, zippers and an included tongue jack cover to reduce sun damage and water staining. It stands out for its six-layer non-woven construction and integrated straps that help keep the cover secure during windy conditions.

Key Features

• 6-Layer Non-Woven Fabric: Provides a balance of waterproofing and breathability to protect the exterior from sun, rain and snow while reducing trapped moisture.
• Wind Resistant Design: Reinforced straps and wind-resistant materials keep the cover tight and reduce the chance of lifting or tearing in gusty weather.
• Side Vents and Zippers: Vents promote air circulation to limit condensation and zippers allow temporary access without removing the entire cover.
• Full Travel Trailer Fit: Sized 252 in L x 105 in W x 108 in H with an extra 12 in length to accommodate ladders, spare wheels, air conditioners and other external accessories.
• Complete Accessory Kit: Includes front and rear straps, bottom straps, extra-long strap, gutter spout covers, ladder cover, tongue jack cover and a storage bag for organized storage when not in use.

Who It's For

This cover is ideal for travel trailer owners with vehicles roughly 18 ft to 20 ft in length who need seasonal or long-term outdoor protection. It suits owners who value simple installation aided by zippers and vents, and who want a cover that accommodates common external accessories like ladders, spare tires and air conditioners.

Those who should look elsewhere include owners of nonstandard-shaped trailers that exceed the stated dimensions or people who want a heavy woven or fitted custom cover for year-round marine-level waterproofing; this product emphasizes a waterproof, breathable non-woven fabric rather than a fully custom, rigid shell.

Pros & Cons

Pros

• Durable six-layer non-woven fabric balances waterproofing with breathability to limit black streaks and moisture buildup.
• Built-in vents and side zippers make installation and temporary access easier without removing the cover.
• Comprehensive straps and accessory pieces, including a tongue jack cover and storage bag, improve fit and convenience.
• Extra 12 in length and large dimensions accommodate common external accessories for a better overall fit.

Cons

• The non-woven fabric is durable and waterproof but is not a rigid custom-fit cover, so owners seeking a tailored, form-fitting shell may prefer a different option.
