I am in the middle of a camper rebuild and remake I am to the point where I trying to decide on a new skin. First the are I have to cover the sides are 44" wide by 11' 6" long and the front is 44" W and 7' long. I thought about T-111 stained but I have found a local deal (I think) on aluminum sheets 4X12 Alcoa 2024 aircraft stuff the ad says 065 on the thickness. I like the idea of them being long enough no seems except the corners. 100.00 per sheet also as far as substrate the camper walls are 1x4 on edge with pink fiberglass in the voids. now I will defer to the experts here as to what you guys think. PS im new to the forum love it.
