Hi Wisconsin Deetster,
I never rebuilt a classic trailer like yours, about as close as I have come was rebuilding an older "late 60's" cabover camper in the early seventies and building my cargo conversion.
With that said, it would really help if you posted some pics of what you have now and areas of damage. I remember when I bought my old camper, there was damage to some of the skin in several places and to a couple running lights and skin where the previous owner drove under something too low. I carefully removed the trim, damaged skin sections, and running lights ... There was no rot and I was able to replace and reinforce a few pieces of damaged structure.
I was able to find matching trim, skin, and lights and replaced these using a good quality 100% silicone sealer at all junctures. I repaired damage to the interior, sanded and refinished all the wood inside, insulated the floor from the underside of the camper, and used it for another 10 years ... even making a trip from southern Arizona to northern Minnesota, where I lived in it for most of the summer while working in Keewatin, before heading back home.
The point being ... the camper looked pretty rough when I bought it, but the damage was really not too bad ... most of it was cosmetic except for the outer skin and a little structure damage that had some water damage. A little TLC, polishing, and wax ... When I finished, you couldn't really tell that it had been damaged ...
Just maybe ... you won't have to disassemble every piece to repair and refinish ... Just thinking out loud ...
