Based on their size, luxuriousness and number of amenities, motor homes are categorized into three classes--Class A, Class B and Class C. Class A is the top-of-the-line model, followed by Class C and Class B.
A Class A motor home is built on a specially manufactured bare vehicle chassis and is available with an engine powered by gas or diesel.
A Class A motor home is fully equipped with kitchen, dining and sleeping facilities. Available with optional slide-out extensions, some also have a washer and dryer.
The size of a Class A motor home, according to the Family Motor Coach Association, ranges from 21 to 45 feet in length, with sleeping accommodations for up to six people.
As of 2009, the cost of a new Class A motor home, as listed by the Recreational Vehicle Industry Association, ranges from $58,000 to $400,000.
