The Jeep Gladiator (or Jeep Pickup) is a full-size pickup truck based on the large SJ (Jeep Wagoneer) platform that was built and sold under numerous marques from 1962 to 1988. The Jeep pickup design was noteworthy for being in production for more than 26 years with only minor mechanical changes. The Gladiator was the basis of the first post-war U.S. Army trucks designed to be civilian vehicles and adapted to military use.
