There sure is a lot of speculation about quality, labor force, factory size and location.
When Detroit or the Japanese have a brisk upturn in sales does the car quality take a nose dive?
The fact is TTs are built to a market price point. The construction methods are unique to the industry. What might be shoddy or poor design in home construction may be acceptable in the RV world. But then, what might be acceptable in a Chevy might be shoddy in a Ferrari.
There are classic blunders for sure, and every time I have to delve into the inner workings of my 7 year old TT I am amazed at the short cuts I find.
But that is the nature of the beast. If you want better design and assembly practices, be prepared to pay more. The RV industry has figured out how to give the majority of the public what they want at a price they are willing to pay. I would not expect any significant changes any time soon.
