Not a solid 1 piece floor
What surprised me was that it does not appear to be one solid piece of floor in my coach. There appears to be 4 or 5 pieces laid down from front to rear. I can feel the seems when walking barefoot. I guess, this was a good thing in the bathroom as it only ruined about 2 or 3 feet of floor. There was a definate straight line break where the rot stopped and solid floor began. The DW and I have decided though that if anything else major goes, we will trade it off and replace it. Fingers crossed I don't have to take that bath.
