The concept truck is also 79.1 inches tall and tips the scales at an environmentally…unfriendly 9,300 lbs (4,218 kg), or close to 2.5-times as much as a Mercedes-Benz E350 sedan. Ram says the Long-Hauler has a maximum Gross Combined Weight Rating of 37,500 lbs (16,783 kg).

Power comes courtesy of a 6.7-liter inline six-cylinder Cummins Turbo Diesel engine rated at 800 lb.-ft. of torque, which is hooked up to a six-speed Aisin automatic transmission with four-wheel-drive transfer case coupled to a 4.88 Dana 110 axle with dual rear wheels. To quench its appetite, the Detroit firm’s engineers fitted the Long-Hauler with three fuel tanks with total capacity of 170 gallons (643 liters).

Other highlights include the full Kelderman Air Suspension and 19.5-inch Alcoa aluminum wheels, while Ram customized the apparently spacious 2+2 interior with several options such as a DVD player with overhead screen for rear seat passengers and a rear center console that includes a refrigerator, cup holders and tray tables.

The Auburn Hills automaker said that while only a concept for now, it will show off the Ram Long-Hauler across the country over the next eight months “to gauge public opinion” for a possible production version.
