Have a 1992 Coachman Royal, 36' diesel pusher. Has been mechanicly reliable for many years. Three or four years ago I noticed the driver side wall was pulling away from the floor, could see highway. Took it to a body shop that repairs M/H's and large trucks. He secured that side. Now the passenger side is pulling away even worse. Seems the side wall wood rots and the fasteners fail. Does anyone have experience with this?? I'm trying to fix it without going broke so I can sell it with a clear conscience.
