Look carefully at storage capacity. When you start being in the RV for more than a week or more, you will find you will want more options for clothes and more. Remember that the driver's and passenger seat in a class A become part of the "front" room furniture. When we snow bord we need warm and cool/cold weather clothing.
To us Class A's offer better visibility driving, more comfort and flexibility, more storage capacity and MUCH larger storage tanks. Your need may be very different than ours. Good luck in your search for your perfect RV!
