Sun, rain, sleet and snow can damage your RV’s exterior. Protect your investment with Camco’s ULTRAGuard RV Cover. The cover fits 10 to 12-foot long pop-up campers. Cover dimensions are 150-inches (L) x 46-inches (W) x 87-inches (H). The cover’s top is made of a three-layer material (outer layers consist of spunbond polypropylene with an inner layer of microporous breathable film), while the sides are made of two, extra-durable layers of spunbond polypropylene. Not only are these materials extremely durable, they are also breathable and help protect against the elements. Covered air vents help stop trapped moisture and billowing in high winds; they also keep the unit cooler. To cover your RV properly, the front and rear cinching straps reduce loose fabric and an underbelly strap system provides a fastened fit.
