Hello, we just purchased a used 2008 Access 29T (in great shape with only 21k miles, Ford chassis w/v10) but we have only had it for a short time so I can't say I have much experience with it. But, we chose it because after looking at many used units, we felt the Winnebago was a better quality level coach (at the price/age point we were looking at) than most of the other brands of used coaches we looked at. They seemed to of held up better over time and use than the other brands, and have a little more of attention to details (fiberglass roof, soft lined interior ceiling, digital thermostat, etc.). Granted, how well the owner takes care of it plays a big role in how a used coach hold up of course, but it just seemed to us that the Winnebago's were nicer. Winnebago's website is good too, they have a page you can put in your coaches' serial number and it will bring up the build sheet, showing every option/part on the coach. That's how I found out it had the upgraded 14800 btu a/c rather than the standard 13500. I don't think the private owner that I bought it from even knew that as well as some of the other details of the coach. The 29T with the dinette slide has plenty of room for my 3 person family as well as occasional friends/family that may come along, and it has plenty of internal and external storage for us. The only negative I can find is that the shower is smaller than most of the other coaches we looked at, but then the separate bathroom is bigger than most, it's a trade off I guess.
As I said, we haven't had it long enough to give an experienced review, but so far we like it and are really happy we found it. Good luck!
