Designed specifically for molded fiberglass camping trailers in the 10-13 ft range, this Classic Accessories PolyPro 3 cover delivers triple-ply top protection against rain, snow, UV rays, dirt, and road grime -- with a built-in air vent system and elasticized hem to keep things snug and moisture-free all season long.
Pop-up campers and molded fiberglass camping trailers have rounded profiles and low rooflines that standard covers handle poorly. Classic Accessories designed the PolyPro 3 series specifically for these shapes -- the cover conforms to the contours of your trailer rather than ballooning or pooling water.
The triple-ply PolyPRO3 top panel sheds rain and resists UV degradation, while single-ply PolyPRO1 side panels balance weather protection with breathability. Together they prevent the trapped moisture that causes mildew, delamination, and interior damage during long storage periods.
Thick, three-layer top panel blocks rain, snow, and UV rays while resisting nicks and scratches that degrade a trailer's gel coat finish over time.
Air vents reduce wind-lift stress on the cover and allow interior moisture to escape, preventing mold and mildew buildup during extended storage.
Elasticized hem corners and adjustable front and rear tension panels pull the cover tight against the trailer body for a secure, custom-looking fit.
Integrated rope attachment system and included toss bag let you thread the cover under the trailer without crawling on the ground.
Classic Accessories uses a two-zone fabric strategy on the PolyPro 3:
Fitting a cover on a compact fiberglass trailer solo can be awkward. Classic Accessories addresses this with a few practical design choices:
The cover ships in a gray and white two-tone colorway that is standard across the PolyPro 3 line. The neutral color reflects some solar heat rather than absorbing it, which helps keep the trailer cooler during summer storage.
