Still searching for a better multirole 4x4 solution, the US Army gave thought to yet another light truck requirement which fell to Ford in 1951. Ford engineers returned with what would become the official successor to the M38 line - marking the end of the World War 2-related Jeeps. The Ford submission was designated in US military nomenclature as the M151 to which the further technical acronym of "Military Utility Tactical Truck" (MUTT) was given. Despite its clear Willys MB/M38 influence, the vehicle proved something of a large departure from the wartime Jeep.
The M151 was specifically classed as a "1/4-ton light tactical truck" and powered by a 71-horsepower Ordnance Continental 4-cylinder, gasoline-fueled engine. This was mated to a 4-speed (1 reverse) transmission system. Dimensions included a length of 133 inches, width of 64 inches and height of 64 inches. The engine was fitted to the front of the vehicle in a conventional automobile arrangement. Body construction utilized a monocoque steel body/frame approach unlike the separate steel tubing / steel frame approach to the Willys series and promoted more internal space, a higher ground clearance and lower center mass. Rounded inlaid headlamps continued the "Jeep" appearance though, the MUTT being a Ford-centric product, the grill was comprised of horizontal slats instead of the trademarked vertical lines of the Willys product. The wheels were set at the extreme corners of the frame. The driver sat at center-left with a passenger at center-right. The forward windscreen, as in earlier Jeeps, could be collapsed over the hood to provide unfettered access for long-barreled weapons such as recoilless rifles or similar. Additional passengers could be transported across bench seating at the rear or they replaced by supplies and equipment.
The MUTT departed from conventional Jeep design in one major way - its use of independent suspension unlike the original's solid axle arrangement. The new system allowed for better cross-country performance and, coupled to the stronger engine - improved performance across the board. However, these changes came at a price - it was later found that M151s were considerably more prone to rollover accidents when taking turns at speed or under heavy mission loads. The primary culprit was found to be the rear wheels which tended to slide under the frame during such actions, leading to rather lethal circumstances that followed. As many drivers were conditioned to the more rigid driving qualities of their Willys MB and M38 models, it made for a more attentive experience when attempting to control the newer M151. It was this rollover issue that prevented the M151's civilian sale - unlike previous Jeep lines.
