I bought a used '15 25UDT and have a couple of minor bugs, but nothing like yours. Dealer left old warranty paperwork from PO, they had to re-caulk the tub as it would leak during use. My fridge works fine, but the speakers quit working (head unit still powers on) and the shower water pressure is a bit lacking. Recently found the welded brace on the front part of the fresh water broke, going to have to patch that when I get some time. I usually don't fill up all 110 gallons so I'm not in a hurry to fix it.
