The header describes my question.
I bought the trailer with known flooring issues and have the old area cleaned up above the foam.
Find that it has an aluminum frame which protected most of the bathroom. Damage is limited the the hallway adjacent to the bath.
The trailer is otherwise immaculate inside and good outside. Slides work well (BAL) and are not involved I. The leak--other than the front slide lower corner may have been where the leak originated. Unsure, but the trailer was parked on a slope with slides extended for several years.
I'm turning it into a tiny-home. The front toy room is ideal for such.
Anyway, the flooring is an odd size (13/32"?). Might be common in some other application?
Disassembled the queen bed and installed a twin, and found very similar plywood used on the bed storage top.
The OEM flooring has a paper like material bonded to both sides.
This weekend I'm going square up the removed borders and get on with this project.
Thanks for any ideas on substitutes for the flooring plywood. It isn't standard plywood...much stronger and less flexible.
