The real work won't get underway until late winter. At that point, we'll rent a dumpster and start gutting. We'll save anything that is original to the interior or that might be salvageable for another trailer.
After emptying it out, Colin and his techs will remove the lower half of the interior shell and tear out the rotting floor. When they get it stripped to that point, we'll be able to clearly assess what kind of frame work we'll need to do.
For now, I just need to be patient and dream about camping in warmer weather. . .
