This unique 1970 Dodge D-series truck called “Rollin’ Charcoal” was built by Plowboy Diesel in New Douglas, Illinois. The idea for the project started when someone joked there was enough room in a 1st gen D-series truck to fit two engines. After measuring the 1st gen couldn’t fit two but the 2nd gen D-series could. The truck rides on a custom frame with straight axle front, triangulated 4-link rear, air bags and air brakes. Under the hood sits a pair of 5.9 L 6BT inline-six engines each with compound BorgWarner turbochargers. The drivetrain consists of a custom gear case that connects the output of both engines into one shaft for the Track Master 47RE four-speed automatic transmission. The charged air is kept cool thanks to a very large intercooler with four electric fans while engine coolant runs through the frame to three radiators in the bed.
