Class A motor homes are available with engines powered by gas or diesel. Class A diesel motor homes with the engine located in the rear, commonly called diesel pushers, are the largest and most luxuriously equipped of all motorized RVs. Class C motor homes are smaller, less expensive versions of Class A models.
According to the Recreational Vehicle Industry Association, the cost of a new Class A motor home ranges from $58,000 to $400,000 as of September 2009. A new Class C motor home costs from $48,000 to $140,000.
The size of a Class A motor home ranges from 21 to 45 feet in length, according to the Family Motor Coach Association, and sleeps up to six people. A Class C motor home ranges from 20 to 35 feet in length and sleeps up to eight people.
A Class A motor home is constructed on a bare specially made motor vehicle chassis. Most Class C motor homes feature a manufactured van frame with an attached over-the-cab section. Some Class Cs are built on a pickup truck chassis.
Class A motor homes, because of their size, wheel base and lower clearance, are typically more difficult to maneuver than Class C motor homes.
