Built for serious storage duty, the Classic Accessories PolyPRO3 Model 6 cover wraps your 30 ft to 33 ft travel trailer in three layers of weather-fighting polypropylene fabric. Whether you're storing through a harsh winter or parking through a long summer, this cover keeps UV rays, rain, snow, bird droppings, and road grime off your investment -- without trapping the moisture that ruins finishes from the inside out.
A poorly fitted cover causes as much damage as no cover at all -- constant flapping abrades paint and graphics, and pooled water works into seams. Classic Accessories addressed this with adjustable front and rear tension panels, elasticized hem corners, and an integrated rope attachment system with four connection points per side. The result is a snug, stable fit that stays put in wind without pulling against your trailer's finish.
The included toss bag threads the integrated rope under the trailer, eliminating the need to crawl under your rig during installation. Small detail -- big difference on a cold morning.
Heavyweight polypropylene top layer sheds rain and snow while the inner layer protects your trailer's surface from abrasion. Middle layer adds structural integrity.
Roof vents reduce internal condensation and prevent wind lofting. Moisture trapped under a cover accelerates mold, mildew, and oxidation -- venting fights all three.
Eight anchor points total (4 per side) with an integrated rope channel and toss bag. Cover stays secured in sustained wind without straps digging into painted surfaces.
Front and rear tension panels let you dial in fit across the range of 30-33 ft trailers, accommodating slideouts and varying roof profiles without excess slack.
The "3" in PolyPRO3 refers to the three-layer laminate construction. The outer face is a solution-dyed polypropylene that resists UV degradation and is treated for water repellency. The middle layer provides strength and tear resistance. The soft inner liner makes direct contact with your trailer's finish and resists scratching during wind movement. Compared to Classic Accessories' entry-level PolyPRO1 (used only on the side panels of some models), the PolyPRO3 laminate is used throughout this cover for consistent protection on all surfaces.
Classic Accessories designed the Model 6 for one or two-person installation. The toss bag system significantly reduces the crawling-under-the-trailer step that makes large covers frustrating. Follow this sequence for best results:
The PolyPRO3 Model 6 is built for seasonal and long-term outdoor storage -- the conditions that cause the most RV surface damage. It is also useful for short-term covered parking when a permanent structure is unavailable. Common use cases include:
