Own a large RV? Give your vehicle the protection it needs against the elements by choosing an 18-foot wide RV carport from our store. A storage plan is part of owning any seasonal vehicle, and RVs are no different. An affordable and durable shelter, our 18-foot wide RV carports consist of a galvanized steel frame and a polyethylene cover. Once secured into the ground, the steel frame holds up to most weather conditions. Surrounding the metal frame, the polyethylene shields your vehicle from UV rays and water. To make sure your vehicle stays dry and in good condition throughout the winter, go with an 18-foot wide RV carport.
