I am sorry to say that the floor is not solid and broke up like paper when I
started to probe the wet spots. You are right it must have leaked for a very
long time. Some previous owner tried to remove the sub-floor between the
seats and was unsuccessful (stripped all the screws). Probably why previous
owners sold it?????
I wish I had design drawings for the coach so I could see exactly how the
floor is constructed, that way I could get a good repair. Anyone have them????
I am fortunate that I have a complete cabinet shop (another expensive
hobby), and a large facility to work in. All I need is the design
information.
I have now removed a portion of the floor through to the foam insulation,
approximately 24" by 18" of the plywood in front of where the tank was
mounted forward to the aluminum skin section. Than a section about 6" wide
across in the direction of the generator to the aluminum enclosure. The
good news if one is optimistic is that the plywood ends at the generator
enclosure, and seems to be one piece through to the propane tank
compartment. I have not been able to figure out whether the plywood extends
in one piece into the propane compartment however. The propane compartment
floor seems to be OK at first glance.
When I replace it I will use true marine plywood soaked in cuprinol to
ensure that it will never happen again.
