If you want your RV to maintain its appearance over the years while saving money on maintenance costs, protect it with a premium full-coverage cover by Coverking. Not all covers are suited to the task of long-term protection. Realizing this, Coverking's in-house textile engineering team went to work to find the best material that would protect against the weather anywhere in the country; a material that reflects the Arizona sun, keeps the Florida rains off and blocks out the snow. Presidium™ 300-denier polyester is the result of their effort. The silver coating on Presidium reflects sunlight, and has a water-resistant coating to keep rain and animal droppings from damaging the vehicle's finish. The 300-denier construction is a strong, heavy weave that will resist abrasions. Presidium is soft to the touch and will not scratch the surface. All of this is accomplished in a cover that is easy to install and will store without the bulk associated with premium fabrics. Coverking RV Covers are TS16949 and QS-9000 certified, and all materials used in their construction are tested and OEM-approved. Sizes are available in a variety of configurations to fit Class "A" RVs. Measure overall length from front bumper to farthest rear point, including the spare tire or ladder, if applicable. One-year limited warranty.
