I own a 2016 Thor Siesta Sprinter. Seems to be well constructed, high gloss wooden cabinetry, reclining theater seats, Twin beds that also convert to a king size bed. Fit and finish are good in most areas but there places where the trainee may not have been supervised. All problems have been minor and readily addressed by the dealer. In over 9000 miles, I've averaged 16+ mpg, not towing because it has not been necessary. (Did rent a car to go into Canada on visit to Niagara Falls)
Judging by comments on most RV boards, quality control is an industry wide problem. Winnebago and Thor are not the only ones taking hits.
It really pays to do a thorough PDI before accepting the RV. I've replaced missing screws, tied up cable runs, tightened nuts and bolts and connected the antenna to the cabin stereo. Probably pretty common for today's RV's.
I down sized from a GeorgieBoy 36ft Dp last June and enjoy the smaller RV.
