Rotten Floor in my Outdoors RV

Yes. We purchased a 2006 Starcraft that was three years old. Several years later, the floor started developing soft spots. I pulled up the floor, followed the water tracks and discovered that there was a leak in the shower. The water was leaking into the space between the bottom plastic barrier and the chipboard floor and had saturated the insulation. I replaced the rotten floor with some marine glued plywood and replaced the insulation under the floor. I added venting and also ran a dehumidifier to try to pull all the water out of the lower wall plates. Once the water gets into those closed spaces, it's almost impossible to get it out. Several years ago I noticed that the front part of the frame was notching into the diamond plate on the front of the trailer and an inspection revealed that the frame was fine but the trailer was settling down on the frame. Last fall we had a 1' piece of rotten floor plate fall out of the back and we finally accepted the fact that the trailer was going to require more repairs than I wanted to put into it so we traded it in for a new one.
