Keep your investment protected year-round with the Classic Accessories PolyPRO 3 Model 7T. Built for travel trailers and toy haulers in the 33 to 35 foot range, this cover combines a heavy-duty triple-ply top panel with breathable sides, an integrated air vent system, and a positive tie-down rope system -- so your rig stays covered and the cover stays put.
The PolyPRO 3 series is Classic Accessories' mid-grade cover line, stepping up from basic single-ply tarps with a construction approach that differentiates the top -- where UV, rain, and snow loading hit hardest -- from the sides, which need airflow more than raw thickness.
The triple-ply PolyPRO 3 top is denser and more puncture-resistant than the sides, while the single-ply PolyPRO 1 side panels stay lightweight and breathable to prevent interior moisture buildup. This two-material strategy is what separates purpose-built RV covers from hardware-store tarps.
Heavy PolyPRO 3 fabric on the roof section resists rain, snow weight, UV degradation, and abrasion from tree debris and wind-driven grit.
Single-ply PolyPRO 1 sides allow moisture vapor to escape, reducing mold, mildew, and condensation buildup on exterior surfaces and seals.
Built-in vents reduce wind lofting that can stress seams and pull the cover loose, while also equalizing interior air pressure during weather changes.
Four integrated rope attachment connection points on each side provide positive anchoring. Included toss bag helps route the rope under the trailer without crawling.
Model 7T is sized for travel trailers and toy haulers measuring 33 to 35 feet in length with a maximum height of 118 inches. If your trailer exceeds 118 inches to the peak, or extends beyond 35 feet, this cover will not seat properly -- check your trailer's overall length and peak height before ordering.
Adjustable front and rear tension panels, combined with elasticized hem corners, pull the cover snug against the trailer's profile rather than leaving loose fabric that flaps and chafes. The adjustable custom-fit panels are especially useful on toy haulers with non-standard rear door geometry.
The PolyPRO 3 fabric is treated for water repellency and provides a physical barrier against:
Clean and dry your trailer thoroughly before covering -- trapping dirt or moisture under the cover defeats its purpose. For extended storage in high-wind locations, supplement the integrated rope system with aftermarket cover straps cinched under the chassis rails.
