I all ways by used. I had a 2011 28’, Thor made, Chateau for my last class C. It had some electrical issues. But the coach was made to the same standards as my 2002 Arctic Fox and 2003 Damon Challenger near as I could tell inside. In fact my current coach made by Coachmen, a subsidiary of Forest River, (2014 Leprechaun) is made with the same standards inside. Yes, some small things are made on the cheap with this unit also. As you will find in any mid-priced coach.
The folks that throw “THOR” out there as junk product is just is not right. They make many, many products. Some are better than others. In some cases much better than second up.
In Thor’s case they make so many products you have to hear about the bad ones more than the good ones on the net.
Peace…
