Hi Campmichy, I just bought a 1999 Cub F19, the floor was rotten when I bought it but got it at a good price. The first thing I did was take the floor out all the way down to the rubber membrane. There is no cross support on these trailers just the frame that runs the length of it. I put in 3/4 inch plywood as my base then 3/4 inch foam insulation then 1/4 plywood. Then I went under the bottom and put in 3 cross supports made out of 2x6's. Now I am putting in new linoleum. My floor is strong enough to park a truck on now. The leak was coming from under the trailer where the rubber membrane had come loose from the frame,I haven't figured out how to seal it back up but thinking about using butyl tape and sealing it up. I haven't taken pics yet but will when I finish the job.

Our question is what type of framing is under the floor? Does anyone have a skematic or pictures of the frame? We just want to see what we are dealing with before pulling up the floor. Can we just cut the floor out from around the cabinets and put new plywood down? Are there joists there to support it? Any pics/ideas if you have done this would be great! Thank you!
