I think if it were me I would go to a fiberglass forum, not a wood n stick camper forum for advice. Seems people are posting as if they are experts on Bigfoot.
I had a Roamer, which is similar, so am an expert on that particular model.
Though there is wood in the build, the wood is encased in the fiberglass and 100% waterproof except where the bolts go through, and at those points it was waterproof when it left the factory. Leaks would not compromise these points.
Cabinet wood is not a structure other than the structure for the cabinet and should not be confused with the actual camper structure.
There are molded fiberglass trailers that are just shells supported by wood, but it seems the TCs are not this flimsy.
