My 09 Thor Windsport 32v mad many many items that didnt work. I found the majority at pre inspection and CW took a few iterations to get the bugs out. A year later the awning delaminated and the levelers needed warranty repair. I'm not sure how many of my issues were from Thor or neglect while at CW for 1 year. Thor direct, was excellent to work with.
I think they are of average quality, being a fix it type person will save you much time by not having to deal with the warranty service folks. Having capable warranty service close by is very important. Also, a thorough pre inspection, I spent 2 days on the lot running everything.
Thorough pre inspection, competent warranty service CLOSE BY, and fixing things yourself along with Thor factory support will get you good value. Reliability has been fine since then.
