The Jeep Gladiator is a full-size pickup truck that was in production for more than 26 years. The Jeep J-Series Truck & the SJ (Jeep Wagoneer) have the same platform. Over the years there were 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. There were many versions of the J Truck over the years including the Honcho & J10.
