As a version of the Dodge 3/4 ton WC series World War II military trucks, the Power Wagon was introduced in 1946 as the first civilian 4×4. It was meant to compete with military-based Ford/Marmon-Herrington and GMC trucks. The Power Wagon had an enclosed all-weather cab and an 8-foot cargo bed. It had a 126 inch (3,200 mm) up to a 147" wheelbase chassis. The Power Wagon had a 230 cubic inch flathead inline-six engine. It had a two-speed transfer case. It came with a 4-speed manual transmission with a power take off (PTO) which would send power front or rear for operating auxiliary equipment. It had 9.00/16-8 ply tires on 16×6.50 inch 5-bolt wheels. In 1961 the 230 engine was replaced with the 251 cubic-inch flat head six.
