Loose hinge pins sounds like a great idea. I didn't think about the weight and RJ's mount would work. If I could figure a way to secure that then I could just leave it in place. RJ, do you have a link to that thread? KJ, There's less room on my roof than it appears. I have room for those two but not sure about anymore than that. I have BARELY enough room for two 230W panels (which more than likely there isn't room for two) and maybe one 140W. The only reason for not flat mounting them is I just don't feel like doing anymore work on the MH but I'd like to enjoy some solar in the meantime. Maybe I'll mount them later on.
