Then the other half of the story (insert sinister organ music here). Here is a couple pics of the other side of the trailer (right side). Haven't really decided how much of the cabinetry to leave in place but thought I'd pull the drawers and open the cabinets and get an idea how to reroute the electrical in case I decided to lose the cabinets and drawers... when I did I noticed a soft spot in the floor in the rear of the trailer. [] I pulled up a bit of flooring (was planning on carpeting over it anyway so figured a few chunks missing wouldn't matter) and found this (final pic in this post)... Yep, there's lots of soft, wet, rotten wood under there. Not all of it is that soft and wet but the back corners are practically turning to dust and there's that pretty black color that pretty much tells me it's all absorbed a little dampness over the years. Now the big question is what to do about it. I don't think I can tear it ALL out 'cause it appears to me (not sure yet) that the sidewalls sit on this base plywood. If I tear them out as well what's left?? Can I/Should I just buy some 3/8" waterproof ply and cut it to size and burying all this underneath?? With just a little liquid nail and some careful measuring and cutting I could piece it in... maybe just 4-5 individual pieces and then caulk around the edges to sort of seal it to the sides?? Would give me a good base for screw eyes or whatever to tie planes to... Anyone faced this?? I'm not looking for perfect here but would like to have a reasonably solid/level floor. Guess I could strip the rest out (all the cabinets etc..) 'till it's just a box and then start pulling all the sidewalls and the floor up as well. Anyone know how the floor is held in place?? The sidewalls? How far stripped down should I go until I'm going to be forming new sheet metal ??
