The Dodge Power Wagon is a four-wheel drive medium duty truck that was produced in various model series from 1945 to 1980 by Dodge. The Power Wagon name was revived for the 2005 model year as a four-wheel drive version of the Dodge Ram 2500. As a nameplate, "Power Wagon" continues as a special package of the four-wheel drive version of 3/4 ton Ram Trucks 2500 model. The original civilian version, commonly called the "flat fender" Power Wagon (FFPW) or "Military Type", was mechanically based on Dodge's 3/4-ton WC series of World War II military trucks. The Power Wagon was the first 4x4 medium duty truck produced by a major manufacturer in a civilian version. It represents a significant predecessor to the many modern four-wheel drive trucks in use today. It was marketed as the WDX truck. Until about 1960 it was internally known by its engineering code T137 – a name still used for the original series by enthusiasts. Following Chrysler Corporation policy of badge engineering to provide a greater number of sales outlets overseas, Power Wagons were also marketed around the world under the Fargo and De Soto badges. Starting in the 1957 model year, factory four-wheel-drive versions of the Dodge C Series trucks were produced and sold as the W-100, W-200, W-300, and W-500, alongside the older Power Wagon. The pickups had the "Power Wagon" badge on the fender. The older design Power Wagon was marketed as the "Military Type" to distinguish it from the styled pickup versions. Later the "Military Type" was given the series number W-300M, and ultimately WM-300. The heavy-duty four-wheel-drive W-300 and W-500 trucks were marketed as "Power Giants". The four-wheel-drive version of the Dodge Town Wagon also got the "Power Wagon" badge. The "Military Type" sales in the United States ended by 1968, because the vehicle did not comply with new federal light-duty truck regulations. The "Power Wagon" options continued on the Dodge D-Series through the 1980 model year. For the 1981 model year, "Power Ram" became the marketing logo for the medium-duty Dodge trucks, and the "Power Wagon" name was not used until the 2004 revival. Civilian 1-ton Power Wagon "Military-Type", Flat Fender Style" (1945-1978) The Military style Power Wagon had three series during its lifetime, with different model numbers. The nominal one-ton rated Power Wagon's gross vehicle weight rating (GVWR) was 8,700 pounds. Its maximum payload was 3,000 pounds. It
