Customers searching for their first recreational vehicle often ask us, “What is a Class A diesel pusher?” We are here to explain. We will explain what defines a Class A Diesel Pusher, as well as what defines each “Class” of motorhomes.

Class A:

Class A motorhomes are generally constructed on either a commercial truck chassis, a specially designed motor vehicle chassis, or a commercial bus chassis. Class A motorhomes resemble a bus on the exterior featuring a flat or vertical front end with large windows.

Class A Diesel Pusher:

Class A diesel pusher motorhomes are typically Class A motorhomes that are powered by a diesel engine mounted in the rear of the RV.

Class B:

Class B motorhomes are generally built using a conventional van. Depending on the manufacturer or model, some exteriors have a raised roof that has been added. Some Class B motorhomes are strictly upfitted on the interior with the exterior untouched by the RV manufacturer. For example, our Airstream Interstate, Winnebago ERA, and a number of Roadtrek models are built on the Mercedes-Benz Sprinter Chassis.

Class C:

Class C motorhomes are built on either a truck or van chassis, with an attached cab section overhead. Class C motorhomes are often based on the popular Ford E450 engine, chassis, and cabs. A large Class C can also be based on a larger truck such as a Ford F650. Mercedes-Benz, Dodge and Chevy are other popular choices. They are characterized by a distinctive cab-over profile, the “cab-over” contains either a bed or an entertainment section. For Example, the Itasca Navion and Itasca Viva! are Class C motorhomes.
