Thinking about going from m MH to TT who makes quality units

I'm not going to get into quality issues, because they certainly exist no matter the background of the workers. However I can say first hand that there definitely are true Amish workers in the plants in northern Indiana. They start very early in the morning, and are done by early afternoon. You'll see them on bicycles and horse carts heading down all the rural roads at the end of their shifts.

Now, are they "craftsmen"? Not in most RV factories. So "built by Amish craftsmen" is half right. :)
