Ford M151 MUTT

The Ford M151, or officially: Truck, Utility, ¼-Ton, 4×4, was the successor to the Korean War M38 and M38A1 Jeep Light Utility Vehicles. Despite being a clean-sheet redesign, it almost completely retained the same vehicle concept, dimensions and weight. But contrary to all prior U.S. 1⁄4-ton jeeps, based on the 1941, World War II Willys designs, the M151 has a unitary body and frame, and pioneered replacing leaf-sprung rigid, live axles front and rear, with all-around independent suspension and coil springs. The M151's four inches (10 cm) increased wheelbase, and 2 inch (5 cm) wider body and tracks, combined with the benefits of its integrated body, gave just enough extra space than the cramped prior jeeps, as well as a more planted stance, with greater side-slope stability.
