All-season protection purpose-built for large travel trailers. The Overdrive PolyPro 3 Deluxe layers a thick triple-ply top over breathable single-ply sides, adds an integrated air vent system, and finishes with zippered access panels so you don't have to remove the cover every time you need to get inside. A toss-bag rope attachment system means no crawling under the rig to run tie-downs.
Large travel trailers sitting in storage face constant threats -- UV degradation, wind-driven rain, heavy snow loads, dirt accumulation, and surface scratches from debris. A lightweight tarp won't cut it. The PolyPro 3 Deluxe is engineered as a fitted, purpose-built cover that addresses each of these failure points without trapping moisture inside and causing the mold and mildew problems that plague cheap covers.
The triple-ply PolyPRO3 top panel is the workhorse of this cover. It sheds rain, blocks UV, and resists the abrasion of wind-blown grit and small debris. The single-ply PolyPRO1 sides are intentionally lighter and more breathable, allowing trapped moisture from humidity or condensation to escape rather than pool against your sidewalls. This combination -- heavy on top where weather hits hardest, breathable on the sides -- is a deliberate design choice that extends both the life of the cover and the finish of your trailer.
PolyPRO3 top blocks rain, UV, and snow while resisting surface abrasion and dirt accumulation across all four seasons.
Roof-level vents reduce wind-induced ballooning and pressure buildup while channeling interior moisture out to prevent mildew.
Front, rear, and side zippered panels allow entry to RV doors and compartments without removing the entire cover.
Integrated rope channels and a included toss bag let you run the tie-down rope under the rig without getting on the ground.
Adjustable tension panels at the front and rear, combined with elasticized hem corners, pull the cover snug against the trailer's profile. This reduces flapping in wind -- one of the primary causes of cover wear and surface scratching on the trailer.
A full-height rear zipper panel accommodates toy hauler rear ramps and doors, so you can access the garage area without pulling the entire cover. This is a genuine functional advantage for toy hauler owners who store motorcycles, ATVs, or bikes inside during the off-season.
