Well, I pulled out everything in the rear of the trailer....and started pulling up the linoleum to see how bad the floor really was. The only soft spot was in the corner.....but the more linoleum I pulled up....the more bad floor I found. Pretty much the entire 4x8 sheet of plywood at the rear of the camper needs replaced. The insulation was soaking wet....I'm sure that didn't help things.
I was able to get the entire section of plywood out, now I'm going to put a fan on it to let it dry out...and then start cleaning up all of the wood around the edges. Install my new bracing, new insulation, new resin coated plywood piece, and then new vinyl flooring on top.
I still wasn't able to find any areas on the trailer were water could have gotten in. Once I get everything cleaned up and dry....I'm going to have my wife start spraying up under the wheel wells, and on every window, light, and sealed up place on the outside of the trailer with a garden hose...and I'm going to stay inside with a flashlight and see if I can see any water getting in anywhere. If it all check out..time for the new floor.
Here are some pics......I never would have though that I was getting into this when I bought this 2011 "well taken care of" trailer.
Would the gaps in the seals on the outside windows let water in? Or does it just run out of the little drain holes on the bottom of the window frame?
The caulk around the outside of the window frame looks very good.
