Need a way to get yourself, four buddies and a whole lot of cargo across the country with the bare minimum of fuel stops? The Ram Long-Hauler Concept is your truck. The rig got a quiet coming-out party at the Mid-America Trucking Show, which was held March 31st through April 2nd in Louisville, Kentucky.

This behemoth of a tow rig sports a 197.7-inch wheelbase, or about as long as your average oil tanker. That much space means it has a full-size eight-foot bed and Ram's four-door MegaCab passenger compartment. In keeping with the oil tanker theme, the Long-Hauler has the capacity to hold an astonishing 162 gallons of diesel fuel, thanks to a 60-gallon auxiliary tank in the bed. That much fuel should give this thing enough range to cross the country in two fuel stops if you aren't too liberal with the throttle.

The Long-Hauler is based on the Ram 5500 commercial truck chassis cab, which comes with a 19,500-pound gross vehicle weight rating. Ram combines that with a self-leveling air suspension on all four corners, a dual-rear-wheel package, 19.5-inch Alcoa 10-lug wheels and an Allison six-speed automatic. Add it all up and you've got a gross vehicle weight rating of 37,500 pounds, which should be enough to handle whatever you throw this hauler's way. Doing the grunt work will be a 350-horsepower, 6.7-liter Cummins diesel inline six spitting out 650 pound-feet of twist.

The Ram Long-Hauler, should it make production, will be aimed at those who need enormous towing capacity and range, but don't want to step up to something like a Freightliner SportChassis just yet. There's still no word on a production timetable or what the truck might cost should it become available.
