Class C RVs are the most common motorhomes. They depreciate quickly and can be bought for relatively little on the used market.
The traditional defining features of a Class C are cutaway van cabin mated to a straight-sided body, and overcab sleeping platform.

longer motorhomes have substantial rear overhang which limits departure angle. Easy to “drag” even in urban environments.
