It's just a concept right now, but Ram's Heavy-Duty based Long Hauler, is already making waves. Based on a Class 5 Heavy Duty Chassis Cab, it features an 8-foot long dually pickup box and extra fuel provisions – a 60 gallon resevoir mounted between the cab and the bed, plus a further bed mounted fuel tank that holds 50 gallons.
That results in a total fuel capacity of 162 gallons, which, combined with the proven Cummins 6.7-liter straight-six diesel and six-speed automatic, should give this truck the ability to cover distances of around 1,600 miles between fill ups when pulling a large trailer (think tri-axle). That means, you could drive this thing from the East Coast to the West, only having to stop for fuel twice.
As it's been conceived for long-distance hauling, this rig is not surprisingly loaded to the gunwhales with creature comforts; adjustable rear foot rests, tray tables, built-in refrigerator and Wi-Fi are just some of the features.
Given that the Long Hauler has a Gross Combined Vehicle Weight (GCW) of a staggering 37,500 lbs, it needs a suspension that is up to the task, as a result the front and rear 19.5 inch wheels and tires are connected to a Kelderman air-bag suspension with automatic self-leveling.
