2006 Winnebago Vectra quality question

[KHart]

I am in the process of looking for my first DP. I am looking for something around 34 to 36 ft used. Other requirement is it must have at least 340 hp (prefer 350 to 400 hp) to aid in towing a car trailer and old car.. My budget is under 100k so I am looking at RVs in the 2006 to 2008+ range. I had been looking at Tiffin and Country Coaches and a few others. An Uncle sent me a link to a 2006 Winnebago Vectra 36RD near him that looks pretty nice but I am unfamiliar with this model and not sure about quality. How is the quality of these earlier year models, anything I should be weary of or look out for. I tried to find reviews but did not have much luck.
