the FOAM is ONLY attached to the wood floor by glue. period. no bolting. the floor wood is bolted to the frame. but the foam is only glued onto the floor. hence my fear that it "would/could/might" blow off. that is why i use the cinch straps, to make sure it is secured to the frame.
mike, there was plenty of glue. i was not skimpy on that part. ratkity will vouch for me on that one. full strenght tb on the foam then canvas. after that i diluted the glue and rolled that on top of the canvas. there is more than one coat there also. i made sure of the glue coverage. so i know that is not my problem.
but i keep going back to the cinch straps being my cause. i know when those straps are on i can not get my door locks to fit right. so i have to lock my doors prior to cinching. so my thinking is that those straps are pulling the foam inward on itself. causing the problem.
so i think what i might end up doing is removing the canvas altogether and start over? or just cut away the center canvas and reapply that only with overlapping on the sides. right now my sides are overlapping on the top. oh heck i am not sure what i will end up doing. must wait and check out the whole camper.
i like the idea of just stripping all canvas off and reapply new, as i was going to repaint it anyway. wonder if i can convice the tearjerkers to come back down for a modification weekend.
