In 1967 Dodge released a Power Wagon pickup version better suited for the pickup truck market. It was based on Dodge's pickup truck line. A big-block 383 V8 engines became an option starting in 1967. From 1961 to 1971 the body was called the "Sweptline". It then offered a more modern body image from 1972 through 1980 with varied grilles and paint colors. In 1975 the 4-wheel drive became full-time with a 2-speed transfer case. This was changed back to part-time 4-wheel drive in 1980 due to the energy crisis. A huge boost in sales followed the 1974 release of the extended "Club Cab," popular with families and camper towing. The 4-door Crew Cab was far less common and is quite desirable for collectors. Utility and function was unmatched by few competing models, as the towing, payload, and snow plowing capacity of the Power Wagon equipped with "Dana 60" 8-lug axles was very popular with road maintenance crews.
