American Motors' Jeep designers based the Comanche MJ body, styling, engineering, and drivetrain on the XJ Cherokee, which had been introduced for the 1984 model year. The Comanche had a somewhat more conventional body-on-frame design behind the cab and a removable cargo box, but retained the unibody construction of the Cherokee in the front half of the vehicle. In the United States where the Comanche and Dodge Rampage were sold they are both considered pickup trucks. By contrast, in other markets the Volkswagen Rabbit Pickup was called the Volkswagen Caddy and considered a coupe utility, not a truck because the cargo bed is an integral part of the body structure and not removable. However this is not the legal definition of truck in the United States where the Comanche, Rampage and Rabbit were all sold.
