customized truck, also known as a "trick truck", and was designed to appeal to young 4x4 buyers. The Warlock featured custom gold wheels, wide tires, bucket seats, and a Utiline bed with oak racks. Optional equipment included five-spoke wheels, bucket seats, tinted glass, chrome rear bumper, and power steering. All had black interiors, with gold accents on the dash and the doors, and a "tuff" steering wheel. The exterior was accented by gold pin striping around the wheel wells and the body lines. The pin striping continued inside onto the doors, dashboard, and instrument panel. Warlock was printed in gold on the tailgate through 1978; the 1979 model instead had "Warlock II" printed. The colors of the Dodge Macho Power Wagon Palomino were the same as a Palomino horse (all Li'l Red Express trucks were Adventurers, though the reverse was not true). The Li'l Red Express was not available for sale in California, Florida, Maryland, Oregon and Washington and did not meet special noise standards in certain locations. Because of this the Midnite Express was born. The Midnite Express was not a factory option like the Li'l Red Express, it was a dealer installed package. Dealers that could not sell the Li'l Red Express used high optioned Warlocks, repainted them metallic black and ordered all of the Li'l Red Express parts through their parts department. The Midnite Express was available for the 1978 model year only. This truck was equipped much like the Li'l Red Express with exhaust stacks, wheels, and gold pinstriping. The Midnite Express was painted black instead of red and featured a "Midnite Express Truck" decal on the door. Most Midnite Express trucks were powered by the 440 engine, instead of the 360 like the Li'l Red Express. All of these trucks were considered "lifestyle" pickups and were marketed to an audience that wanted specialty, personal-use trucks. Diesel The 1978 models also saw the introduction of the first diesel powered Dodge pickup truck. Available as an economy choice in light-duty trucks and B-series vans was Mitsubishi's 6DR5 4.0 L inline six-cylinder naturally-aspirated diesel, rated at at 3500 rpm, and ~230 N·m (~169 ) at 2200 rpm. The diesel used standard Dodge manual and automatic transmissions via specially made adapter plate which had the LA V8 bolt pattern. This rare factory option, VIN code H, was the result of fuel crisis and the collaboration of Chrysler and Mitsubishi.
