Cutaway van chassis are used by second stage manufacturers for a wide range of completed motor vehicles. Especially popular in the United States, they are usually based upon incomplete vans made by manufacturers such as Chrysler Corporation, Ford Motor Company, and General Motors which are generally equipped with heavier components than most of their complete products. To these incomplete vehicles, a second stage manufacturer adds specific equipment and completes the vehicle. Common applications of this type of vehicle design and manufacturing includes small trucks, school buses, recreational vehicles, minibuses, and ambulances.
