Cliff,
I would urge you to consider attending the Hershey Park, PA show in September. It's the biggest RV show in North America and nearly every brand and style will be on display. You can get in them, see what features you like, ask questions, meet dealers, get literature, and really start down the road of making an informed decision. If you go you really need to stay at least 2 days. You will learn more about RV's there in 2 days than you will in a year going to individual dealers, and you'll have fun to boot. My wife and I went last year and are attending again this year. It's an amazing show.
