When I bought mine they were of average quality but offered a lot of bang for the buck.
I think things may have changed though as a friend was shopping for a TT last week and stopped at a WC dealership (Poulsbo RV). He said every one he looked at had something wrong with it. Anything from crooked cabinet doors to (mostly) broken items like a sliding door that was ripped out of the ceiling. Salesman kept saying they would fix everything before he took delivery but who want's to buy something broken?
He ended up going elsewhere and buying a new Arctic Cat.
