I have a 2000 30Q and have been relatively pleased with it. I bought it two years ago. It works just fine for what we do which is once or twice a month to a local state park and a couple longer trips throughout the year.
Check out the outside storage space. I know later models may have more but I find the storage spaces to be odd sized and not enough of it. I found the inside cabinets space adequate but the drawer hardware (sliders) cheap.
Ours has a Workhorse chassis and considering it's 13 years old has been good.
The front seats do not turn fully around, half way which may not be an issue for you, just thought you might want to know.
If you're getting it from a dealer, try to get new tires included in the deal and make sure the tires they put on are new as in current year manufactured.
