What is the difference between a Class A and Class C motorhome or a travel trailer?

Class C motorhomes are smaller than a Class A and have an additional bed over the cab or driver area. Class C's have tighter spaces and a step down into the drivers cockpit. The driving area is more confined much like that of a van or small box truck. Travel trailers must be towed by a truck and the facilities cannot be accessed while on the road. Class A's on the other hand are more like a bus and have large panoramic views for the driver and passengers. They are all one level and more spacious to move around in and generally fully accessible while traveling.  more
