Had this pop up 1 month now. I knew about the rot in the one corner that I have already cut out and replaced. Today, when under the kitchen sink area, I found a lot more, including rot going up the entire corner. The culprit, I am convinced, is the kitchen drain. When we went on our first trip we noticed a small leak there, and the floor was wet when I was under the sink. I am working on fixing this next. This serves as a reminder to make sure to check every spot for rot before buying. I fixed it all in one day, but it was not fun.
