Keep your travel trailer protected during storage with the Classic Accessories PolyPRO 3 Model 1 cover. Engineered for trailers up to 20 feet long and up to 118 inches tall, this three-layer cover combines a durable polypropylene top with quick-drying PolyPRO 1 sides and a built-in air vent system to fight moisture buildup, UV damage, wind lofting, and seasonal weather -- all without crawling under the rig to secure it.
The PolyPRO 3 series is Classic Accessories' mid-tier travel trailer cover line, built for RV owners who store their rigs outdoors through multiple seasons. The Model 1 fits trailers up to 20 feet and ships with everything needed for a snug, secure fit right out of the box -- no separate straps or toss bags to track down.
The three-layer construction pairs a breathable, moisture-venting top panel with lighter PolyPRO 1 side panels that dry fast after rain. That combination keeps the cover from trapping condensation against your trailer's sidewalls, which is one of the main causes of mildew and finish damage during long-term storage.
Reduces wind lofting and vents interior moisture, preventing condensation buildup against trailer walls and roof during storage.
Front and rear tension panels plus elasticized hem corners allow a snug, custom fit across different trailer profiles up to the maximum dimensions.
Integrated rope attachment system with 4 connection points on each side -- 8 total -- keeps the cover anchored in high winds without constant readjustment.
The included toss bag lets you feed the cover over the trailer from one side without crawling underneath -- a practical time-saver for solo installs.
This cover is rated to handle the full range of outdoor storage threats:
The cover is sized at 246 inches long, 104 inches high, and 102 inches wide, designed to fit trailers up to 20 feet with a maximum height of 118 inches. The elasticized hem corners grip the trailer's lower profile while the tension panels at the front and rear pull the cover tight along the sides. The rope attachment system threads through the integrated loops at mid-height on both sides to keep the cover from billowing or shifting in wind.
When not in use, the cover folds down compactly and stores in the included toss bag, which also doubles as the deployment bag during installation. Classic Accessories recommends cleaning the cover with mild soap and water before long-term storage to prevent staining and material degradation.
