The Dodge Power Wagon is a four wheel drive light truck produced from 1945 through 1980. It was reintroduced under the Ram Trucks brand in 2005, and became an official model of the brand in 2013. This early version was based on the WC series of Dodge 3/4 ton Military trucks produced during World War II. The Power Wagon, as a civilian vehicle, continued the lineage of four wheel drive Dodge trucks from the 1930s, proving basic four wheel drive design concepts and representing a significant predecessor to the many four wheel drive trucks in modern use today.
