Dodge built the American army’s ¾-ton trucks — the WC series of 1940–45 and the M37 of 1951–68 — and turned them into the Power Wagon of 1946, the first four-wheel-drive truck a major maker sold to the public. The styled W-series followed from 1957, the Ramcharger in 1974 and the Cummins diesel in 1989; Ram has been its own marque since 2010, with the Power Wagon, Rebel and TRX as its four-wheel-drive flagships.
Dodge’s military four-wheel drives: the WC weapons carriers, command cars and ambulances of 1940–45, the middleweight of the American army between the jeep and the 2½-ton trucks, and the M37 of 1951–68 — about 115,000, including 47,600 M37B1s and some 4,500 Canadian M37CDNs — which served in Korea and Vietnam.
The civilian line: the Power Wagon of 1946 — the first four-wheel-drive truck sold by a major maker, built to 1968 in America and 1978 for export — the styled W100 to W350 of 1957–93 with the Cummins diesel from 1989, and the Ramcharger of 1974–93 with its Plymouth Trail Duster twin.
The modern trucks: the 1994 Ram that made Dodge a contender, the Cummins diesel, the revived Power Wagon of 2005 with lockers, a sway-bar disconnect and a Warn winch, the Rebel of 2015 and the 702 hp TRX of 2021–24; Ram has been a marque of its own since 2010.
