Brother in-law gave his old TT to his daughter which has a square door frame. Niece and her husband were able to re-build. Probably better than newer type radius corner door. On the inside was foam board and cardboard. Replaced insides with some plywood and foam board and used blind rivets. Door is working pretty good, used by a working couple so seldom used except vacations and 3 day holidays. So verdict still out as to long term.
I agree - best bet is probably to rebuild what you have if the skin and frame is okay. Parts are getting tough to find for these old rigs so you may have to improvise.
