Replacing floor in 2005 Stampede

[Tank178]

The floor in our 2005 Palomino Stampede got spongy and soft in several areas. I decided to rip up the old flooring and find out where the leak is and replace the rotting wood. For the new floor I am using the following materials:
- Tar paper
-1/8 hardboard
- Greenboard foam
- 5/16 plywood
- Clear penetrating epoxy sealant (to harden the rotted wood under the walls where it meets the frame)
- Epoxy bilge paint
- Black Dicor lap sealant
- Vinyl planking

After removing the front dinette booth and chest of drawers at the front, I cut out a section of linoleum and saw that the wood was completely saturated. I also discovered that FR used standard white styrofoam (which asorbs and holds water), as insulation. The bottom layer of plywood was also completely saturated and coming apart into a paper-like consistency. I am starting at the front of the camper and dowing small sections at a time.

After cleaning out the rotted wood and allowing the tyvek-like underlining to dry, I layed down a section of tar paper. I cut pieces of the hardboard and painted it with the bilge paint to provide water resistance. The next layer is the green foamboard insulation. The 5/16 plywood is the decking and I painted both sides with the bilge paint.

Once I reinstall the furniture, I will caulk the edges of the decking where it joins the walls. After the furniture is screwed down, I will install the vinyl planking as a free-floating floor.

I will update progress is made.

The first pic is with the greenboard foam put down and the last pic is the vinyl planking samples on top of the old linoleum. We went with the middle- Regency Gunstock.
