Without trying to be a smarty pants, get out, get in some and see what you like. As a previous coach tech for almost 10 years, I'd say make them show you the operation of the day to day items that you need to know. See what is easy to use, and what is not, that's the main thing I want to know when looking at a new (to us) coach.
When I worked on RV's Beaver was a medium easy to use coach. The Country Coaches, in your price range, were on the upper end of hard to get to know. The easiest was always an American coach.
If it makes any difference, since it was said on page 1 or 2, I own a 2003 Flair, gas coach, so I'm not even in your range or class. My post is from a technicians experience.
