I have a 1974 10' Scamp
with a sagging door. The bolts on the upper door have enlarged the holes in the door. The fix seems to be to remove the door, fill the holes with bondo, reinforce the area with fiberglass cloth, drill new holes and replace the door.
I have redone the main cabinet to allow installation of 12v converter, microwave
and 110v fridge
. Will post pics when I find how to do it.
