Class A motorhomes are at the top of the list when it comes to luxury, style and performance in the RV world. Units range in weight from 15,000 to 35,000 pounds and stretch from 30 to 45 feet in length. Describing them as "motorhomes" is no exaggeration. Class A motorhome units come with almost everything one would expect in a home. At the very top of this list is an almost separate category of luxury Class A diesel motorcoaches or diesel pushers, costing $155,000 to 1.5 million or more.
