Bathroom, Day 1
When I first looked at the Overlander, I knew the bathroom floor was soft, but did not realize it had disintegrated into wet mulch. Subsequent investigation revealed leaks on the end cap, RH taillight assembly, and RH backup light were the leading culprits.
The pictures below were taken after the toilet was removed. As a point of reference, the white area in the top RH picture is the black water holding tank. The tiles, which had already popped loose, were removed so I could figure out where it was safe to walk.
