When I first learned the kitchen sink was draining to the black tank the first thing I did was started tracing the plumbing. Pulled out the drawers under the kitchen sink and discovered that the panel next to the stove had a huge crack
Also the top bunk broke the first time my son used it (125 lbs) luckily he didn't get hurt.
Interior door trim not nailed down and just flopping around.
Ridiculous amount of garbage (screws, scrap wood, dust, etc.) in the hidden areas.
Black tank flush valve wasn't working so I had to remove the panel in cupboard in the bunkhouse and the hose was twisted around like a pretzel.
Latches on the Murphy bed and in the storage area not even close to lining up with their holes.
GFCI outlet in the bathroom went bad. Red light on all the time. It's at the dealership now getting that replaced.
TV antenna wouldn't rotate.
I cannot believe my TT made it through quality at the factory! But like I said I have learned a lot along the way and have also learned that this is kind of the norm in the RV industry. Just stinks with it being our first TT purchase after many years of discussing it and finally making the leap to have to deal with all this!
