Full-rig protection built specifically for Class C motorhomes in the 26 to 29 foot range. The PolyPRO3 cover uses a dual-layer fabric system -- a polypropylene top for weather resistance and breathable PolyPRO side panels -- to shield your rig from rain, UV, snow, road grime, and surface scratches while venting trapped moisture before it becomes a problem.
Leaving your Class C parked for weeks or months without a cover invites UV fade on decals and fiberglass, moisture intrusion at seams, bird damage, and surface oxidation. The Classic Accessories PolyPRO3 Model 4 is purpose-built for this size class -- it is not a universal tarp adapted for RV use. The fit points (front tension panel, rear tension panel, elasticized hem corners) are sized specifically for the 26 to 29 foot Class C footprint, so the cover stays put in wind instead of flapping and chafing.
Part number 01-0337 corresponds to Classic Accessories UPC 052963794632. This cover is also referenced by Classic Accessories item code 79463 in older listings.
Front, entrance-side, and rear zippered panels open without removing the cover. Panels roll up and lock with hook-and-loop straps so you can run the engine, grab gear, or access the cab while the cover stays on.
Air vents combined with quick-drying PolyPRO side fabric reduce wind stress and allow interior moisture to escape, preventing mold and mildew buildup during long-term storage.
Integrated rope attachment system and an included toss bag let you thread the tie-down rope under the rig without crawling on the ground -- a real time-saver on solo installations.
Adjustable front and rear tension panels plus elasticized hem corners pull the cover snug around the RV profile, reducing flapping and preventing wind lift during storage.
The PolyPRO3 uses a three-layer construction with a polypropylene outer layer that sheds water and resists UV degradation. The side panels are made from a lighter, breathable PolyPRO material that allows moisture vapor to escape while still blocking rain and dirt. Reinforced corner patches protect the highest-wear areas where the cover contacts slide-out edges and body corners.
Classic Accessories designs the PolyPRO3 to be installable by one person. The toss bag holds the weighted rope end so you can throw it over the roof rather than climbing a ladder on both sides. Installation sequence: unfold cover on the roof, toss rope side to side, pull cover down over each end, tension front and rear panels, secure hem at corners, thread and tighten undercarriage straps.
The cover stores in the included stuff sack. To fit it back in the bag: fold the cover flat first, then roll it tightly from one end -- do not stuff it. Rolling compresses the fabric uniformly and keeps it fitting in the bag long-term.
Three independent zippered access zones run along the cover sides:
Each panel is held open by hook-and-loop straps near the top of the opening, keeping the flap out of the way while you work.
