It’s a 1998 Dutchman, I’m bringing it out to my camp and it’s not going to be moved after it’s out there. I want to do preventative maintenance by upgrading the roof (it’s not leaking or anything at the moment). Like putting a metal slanted roof above or something so the snow doesn’t build up and get super heavy on it. I just don’t really know what I should do, I want this thing to last me as long as possible.I live in north west Ontario. Any advice would be much appreciated!
