Hey all,
Working on the floors in my 76 Elaganza. The second sheet of flooring plywood (from the front) had a significant bowing upward in the center. This had to be fixed (actually I'm replacing all the floor) so that I could start on the interior rebuild. So to inspect what was causing the issue I took my Skill saw, set the blade to just under the thickness of the plywood and made a cut from side to side about 3 inches from the rear edge (8' side). I then just used a screw driver to pop this section of plywood off (much of it actually just fell apart from previous water damage). Anyway what I discovered is that there is foam between the aluminum cover protecting the bottom of the plywood and the plywood, to the point it looks as though the foam is what has caused the floor to buckle upward. The interesting thing is that the the original Norcold frig that I just removed a few weeks ago had all of its insulating foam expand (over the years ?) to the point the doors would no longer shut and it split all the interior plastic by pushing it inward. Also this frig would not come out since the sides were swelled out as well. Hmmm....so it looks like old foam continues to expand (at some constant rate, or accelerated because of temperature, etc ?) Does this sound reasonable. Also then do others have foam between the bottom aluminum and the floor plywood.
Thanks as always...
