I have an Outlaw 29H we bought new last August and we noticed the bathroom floor had a soft spot around the toilet. When you stepped hear the toilet or sat down you could feel the floor flex. We knew it would get worse over time.
We dropped it off in the fall to have a bunch of warranty stuff done. Dealer agreed you could feel the flex in the floor. They contacted Thor and dealer said Thor could either ok them to fix it or Thor could require us to take it back to IN for them to fix.
Took several weeks for Thor to respond to the dealer but they agreed to let the dealer do it. The dealer noted in the service paperwork there was no real support structure in that area of the floor. They ended up removing the black tank and installing 3/4 plywood and adding metal supports. Reading the paperwork it looks like the dealer did a really good job doing what Thor should have done during manufacturing. The floor really feels solid now.
When we picked it up last August, we could also feel a flex in the shower floor. Fortunately there was an access panel so I cut some wood pieces added them beneath the shower floor to keep the shower floor from flexing and eventually cracking. I did that after our first trip out in it.
