For many laymen, indeed for many buffs, any 1/4-ton 4x4 vehicle is a “Jeep.” But the final generation of vehicle in this weight class fielded by the U.S. military had its own name, the MUTT (Military Utility Tactical Truck). Developmental work for what would become the MUTT began in the late 1940s, even prior to the adoption of the M38. Both the M38 and M38A1 were considered interim vehicles until the improved model could be fielded.
Ford Motor Co. was awarded a contract to begin development of a new light utility truck. Light weight was a prime concern. To address this issue, Ford proposed various vehicle designs and materials. Ultimately, the unibody design won favor, and it was tested in both aluminum and steel construction. During trials, however, the lightweight alloy bodies developed stress fractures, and the idea was dropped in favor of a steel unibodied vehicle. The new vehicle, designated M151, was placed into production.
The rear suspension of the M151 was found to sometimes buckle or collapse, particularly when heavily loaded. This was often the case when the vehicle was burdened with mounted weapons and cargo. The redesign featured new high-strength rear suspension arms, with extra bump-stops. Production of the vehicles with this improved suspension, known as model M151A1, began by Willys Motors in December 1963. In January 1964, the name on the builder’s plate of the M151A1s being produced was changed to Kaiser-Jeep Corp.
In 1964, a new round of bidding resulted in Ford regaining the 1/4-ton truck contract and Ford resumed production of the Mutt in January 1965. Ford’s production of the M151A1 continued up through 1969.
