ACE 30.1 has the shower on the left and bathroom on right. I noticed a soft spot in the floor between them. 2 years ago I had a faucet leak in wall between shower and bedroom. They had to repair it several times. Could this be a result of that leak?
That leak is a safe bet for your soft spot. Leaking water can travel or spray. Is it in a place you can access from below? If you don't have a plumbing schematic, call Thor with your VIN and ask for that, and the electrical ones, too.
You'll get suggestions here with more information.
