Goshen lift system. Bought with broken cable. Fixed it to find the front right roof corner is soft. I used Eternabond tape to seal the sides and roof. So it shouldn't leak anymore. The problem is, the wood at the lift post is soft and it allows the corner to sag 3/4 inch lower than the other 3 corners. So the door won't lock in . I'd like to try to get through the summer before trying a roof rebuild. One suggestion I was given is to put a 3/4" spacer in that lift post so it will push that corner up even with the others. I also thought about unbolting the corner bracket and putting a piece of metal in there, and then larger washers on the outside at the bolt heads. That way I can crank it tighter than the wood will allow. I'll try to post pictures of where it's sagging.
