Interesting. When we bought our first RV 11 years ago the dealer drove us to a local stadium then let me drive. He didn't know me so I fully understand. I've been pulling trailers and driving trucks since before it was legal to do so. Took the whee and in half a minute he was relaxed and we then went out on the highway. Fast Forward to last year, we traded up to a DP. Since I arrived at the gathering in a Class A they were a little less apprehensive. One thing however that I feel they should have done is to have given a bit more info on Air Brakes. They aren't the same as hydraulic and you can screw up.
The big things we noticed was noise level, it was missing! The second thing was the ride, Air ride VS Springs. Much smoother. For us floor plan was critical, we were going to have a bunkhouse, this is our third so that was no issue. What we were looking at was could we get to the head with the slide in? Could we sleep in the master bed with the slides in? Could we get to food and eat with the slides in?
If this is your first 'A' you need to consider floor plan, engine, OAL. Seating positions. SIT AT THE TABLE, Stretch out on the sofa, look at the TV, can you? Try to do a day in the life in an hour. If you can't stand to sit at the table, if the sofa is 6" too short, and so on, better to find it out before you buy.
For your test drive, try to get at least half an hour. Freeway, Two Lane, side road, at least one that is not a perfectly smooth flat road, you want a bit of road crown. Windy day? Better yet.
Don't be afraid to walk off, come back another day and compare what you thought to what you see on day two.
