Sun, rain, sleet and snow can damage your RV’s exterior. Protect your investment with Camco’s Pro-Tec Premium RV Cover. The cover fits travel trailers, 18'-20'. The cover’s sides, front and back are made of three-layer non-woven polypropylene, while the top is a three-layer material made of non-woven polypropylene and DuPont™ Tyvek®. Not only are these materials extremely durable, they are also breathable, water resistant and offer UV protection. The cover’s hems and seams are lock-stitched and the corners and other high-wear areas are reinforced to withstand frequent use.
