Looking for our next RV....Considering an A - Advice needed

We have a seriously handicapped daughter, so the class A was a no brainer. She gets the jackknife sofa, the more mobile teen gets the drop down bunk above drivers seats, we take the back bedroom. We can be comfortable, they can eat, drink, watch t.v. while we're traveling. They like it a lot. It makes the travel time go by easier. Economically, it's cheaper to drive a car and get 2 adjoining motel rooms, but not easier or more fun.
