The chassis has been wonderful, I love the ride and the highway driving is a dream. The turning radius is less than I would like and theres a lot of "road feel" in the steering wheel I could do without, but those are livable.
I hear theres a new improved steering Freightliner is coming out with. I would wait for that. Oh, and a few more adjustments in tilt and seat position would be good. I can fix that though.
As for mileage I havent done any trip calculations yet, I'm expecting eight to ten and if I get more than that it will just be bonus!
Theres been a lot of problems with the building or house part of the RV, just a lack of cleanup and attention to detail during the building of it. I think this is inherent to all Thor Rv's, and maybe all new RV's everywhere, like new cars I think they all have a unique set of issues.
Either way you go it will be an adventure!
