Water Leak, Repair Update Feb 12th

A few years ago we bought an '04 Tahoe Lite (yeah right). I did look underneath it before buying. The fabric (Darco?) was intact and didn't see any holes. Got home and with more studying, noticed that the Darco was hanging down in the middle quite a bit. Made a slit with a knife in the middle and it looked like about 5 gallons of water drained out. Somebody had replaced the floor and put new Darco under it but turned the edges up and stapled them to the bottom plate. So, as the siding wasn't properly caulked, water constantly worked its way under the Darco and the way it was attached directed the water directly on top of the fabric where it just collected. So ripped it all out, pulled out all of the wet insulation, dried out the wood joists and sealed it all with pink rigid one inch insulation panels. Glued and screwed it to the underside of the floor and caulked well. Worked great, smooth under there and no water.

I used the CPES on an '85 Wilderness when I had to rebuild the bathroom floor. Was able to save the bottom plate of the walls and bottoms of the studs, so didn't have to rip out the partially rotted walls. Great stuff, gotta wear a gas mask!
