I am building a "larger" (6 x 12) camper. Wondering if anyone has used cellular PVC sheets for walls, floor or, roof. There are several companies you may have in your area such as Versatex, Veranda, Azek ... The material will not absorb water, i lighter than plywood, and is UV stable. Only two issues I can see is the price and expands more (10%? ) more than plywood. I know boat builders us something similar but even more expensive. I appreciate any feedback.
