In the late 1970s, Plymouth decided to try its luck in the off-road SUV market with the Trailduster. It was a two-door, four-passenger, all-wheel drive vehicle identical to the Dodge Ramcharger (via Drivingline). Plymouth offered an all-wheel drive at an affordable price to promote the product in that market and more equipment than Dodge.
But they still had no luck. Therefore, after a couple of years, they discontinued the Trailduster. Today, some Mopar fans claim the Trailduster was more dependable than other Dodge products from the same period.
