The success of the Blazer and the Bronco inspired Dodge to offer its own off-road model they based on a shortened truck chassis and with the closed body style. They called their new model the Ramcharger, introducing it in 1974, along with the identical Plymouth Trailduster.
The base engine was Chrysler’s venerable 225 slant six unit, but buyers could choose between four more engines, including the mighty 440 V8. The power level of this famous big block was not that high for 1974 but loads of torque was more important for off-road driving and pulling the Ramcharger out of the mud.
They presented the second generation in 1981 and discontinued it in 1994. Basically, it was just an update of the original design. This means that Ramchargers are quite common and affordable, so you should be able to find a decent one with ease.
