Hi,
I agree with the Tiffen, Newmar & Winnebago comments for quality, but of course, condition is a huge part of that as well.
The only thing I'd suggest you look at IF you start looking at Winnebago's is to check the chassis for rust. My uncle has a 2007 Winnebago Voyage and for whatever reason, there is A LOT of rust on the sheetmetal of the chassis. Our Georgie Boy is several years older and doesn't have anywhere near the rust his does and we live in the same parts of the country. His did take 2 more winter Florida trips than ours, so his might have been exposed to a bit more salt, but I would doubt that alone could be the reason. Maybe his just received a crummy paint job on the sheet metal? And I haven't heard any one else complain of this on these forums, so perhaps his is an isolated case.
The only other thing I would suggest is IF it's at all possible, I'd recommend you consider something in the 34'-36' range. The extra couple of feet make a big difference for interior space and outside storage. The difference driving is mostly negligible and there shouldn't be that much difference in cost.
Good Luck in your search.
