A friend of mine, who was an RV salesman, told me that Thor quality seemed to go in cycles. From what I have read online, they seem to have hit the bottom. I bought a new 2005 Thor and other than a few minor things, it has been a great Class C RV. My friend said my 2005 was built just after the peak. No, I didn't buy it from him.
Maybe Thor will be pretty good in about 10 years???
I don't really know much about the current RVs. From what I have read, this seems to be a terrible time to buy a new RV. None of them seem to get good reviews.
