I just rebuilt a 2002 Lance 811 with water damage from leaking windows. The sides of the camper are what give the cabover its strength, the framing is just 1x2 wood. There are also diagonal supports that run in those sides, but when the forward windows leak, those rot away and allow the camper to begin to drop. I had to jack mine up in the front and use a laser to re-square it before I re-installed new framing and siding.
Click the link in my sig for the re-build thread, lots of pics. Mine is fiberglas, but they're all built basically the same. The repair isn't difficult if you have basic handyman and woodworking skills. The main thing is the time and a place to work on it, I put a few hundred hours into my build. Then you have to consider that the fridge and appliances are now 22 years old.
I went all the way with new fridge, new converter, new bed, etc etc and I was all in on the repair at about $4k, but when it's all said and done, have basically a brand new camper.

OP can buy a new one for what they will want to fix this one.
