The Classic PolyPro 3 RV Cover shields your vehicle through all seasons and virtually all weather conditions. It is made with heavy-duty triple-ply PolyPro 3 fabric on the top and quick drying PolyPro 1 on the sides to keep rain, snow and debris off of your RV's exterior. Elasticized hem corners can be stretched for a snug and secure fit on the front and rear of this gray/snow white Classic Accessories RV cover, preventing it from blowing away in the wind. An integrated air vent system helps to vent inside moisture so it evaporates more quickly, keeping the cover dry. Installing the Classic RV cover is made easier thanks to an integrated rope management system, and zippered panels grant continued access to your RV's doors and engine.
