Here we have a commerical grade RV cover design that is 40′ W x 50′ L x 16′ H. The customer wanted to enclose (3) sides ONLY and leave the front side completely open to have easy access to get in and out but allowing his RV cover to stay out of the weather at the same time. You would also have to supply the installer with a telescopic lull lift to erect the metal frame for this particular size. Please give us a call today to get a FREE QUOTE.
