We just bought a 59 trailer and have lots of questions.
The subfloor is rotted on all 4 corners and sides. I pulled up 1 corner and found the layer underneath it is warped and peeled back, leaving the underside if the subfloor completely exposed.
My question is: Can I cut out only the ad part of the lower board and replace it with new board, then glue it to the old piece and and seal it back up, or do I need to take off the entire lower layer (I believe called the pan?). Also not sure what the material is, looks a little like masonite, but is very old and worn out.
Here are some pictures.
Please help me understand how to best fix with and where I can get more replacement board for that.
Any other tips regarding fixing the sub-floor are much appreciated!

It's called celotex that was impregnated with asphalt. I replaced it in mine and then covered the bottom with butyl flashing (like they use around windows). It's been 2 years and is holding up fine. But most people seem to replace with plywood and then put truck bed liner on the bottom. I have also seen some folks use a layer of plastic under the plywood...which seems to me like it could be a moisture trap. Mobiltec's restoring the shasta series has an epsiode that covers this. I think he said if he were doing it again he would use something else, maybe just plywood.
