OK. Entire floor from the goucho back is out. As I was removing wood the rot was more extensive than I thought, I also had to cut back to a rail even if the wood was good. I just need to apply rust protectant then I can start putting it back together. It seems the end is in sight and I can stop tearing things apart! I am going to buy marine grade plywood to be delivered next week. I just received the rest of the parts from vintage trailer supply!
