More rotten wood

The shower floor was soft, and I did not want to be taking a shower and suddenly end up under the camper, in my birthday suit.
Rot under shower floor

Rot at entry door, notice the 2 layers of plywood that had been overlayed on the entire floor area.

Removed the back 3 feet of camper floor that hangs out past the truck bed

Building up the new section, 2 layer of 1/2 inch plywood, with braceing and voids were fitted with 3/4 inch dow corning foam board

New section installed, and coated with rubberized automotive undercaoting
