Our TT is a PCW. It had its share of problems, the factory QA is not very good. They drilled through the aluminum framing to run wires and didn't clean up the hole at all. 'Specs subject to change' included a 12 gallon black tank that held 6 gallons (and that's including 3' of 3" pipe!). Side vent access doors for fridge were held in place by the bare minimum of acrylic caulk which proceeded to fall apart first year.. There were other issues that I fixed, mostly minor.
All that being said, not a bad trailer for the price. And now that I've fixed the problems (including upgrading to a 25gallon black tank ;-) it's a good solid trailer.
RV's are complicated, manufacturers seem to get away with poor quality because people keep buying them anyway.
