We were moving at a good clip until we got to the floor. Where the floor isn’t soft from the trailer leaking, it’s difficult to pull apart. The press wood is incredibly heavy and well fastened to the joists, which are 2x4. We tried going at the floor with hand saws, crow bars, hammers, and the like, but I ended up buying a reciprocating saw from Harbor Freight. That's working okay. We're taking it apart in about 1.5 by 5 ft. pieces. It's slow, but coming along. I found a video on Youtube in which young men went at the floor of a mobile home with an ax, but that's not for me. They also cut the steel frame with an angle grinder. Since that's the only info I've seen online regarding actual disassembly of a mobile home, it's probably what I'll try. I'm up for any suggestions that don't involve a welding torch.
