Looking for the ultimate tow rig to pull your fifth-wheel horse trailer, car hauler or RV across the U.S. with just two refueling stops? The Ram Long-Hauler could be all the pickup truck you’ll ever need. We're all over the Long-Hauler, along with our friends at Diesel Power Magazine.

The Long-Hauler name fits the truck’s length and driving range. The 197.4-inch-wheelbase pickup is based on the Class 5 Ram 5500 medium-duty chassis cab commercial truck (19,500 pounds gross vehicle weight). It’s been upfitted with dual rear wheels, an 8-foot cargo box and an extra 110 gallons of diesel fuel capacity – 60 gallons in a custom midship reservoir positioned between cab and bed and 50 gallons in a bed-mounted combo fuel tank and toolbox – for a total of 162 gallons. That’s about 1,600 miles to 2,000 miles of range.

To make the ride as comfortable as possible, the Long-Hauler features Ram’s four-door Mega Cab configuration, which offers the most interior volume of any full-size pickup. For backseat passengers, there are adjustable footrests, tray tables, a refrigerator and Wi-Fi connectivity. It’s also trimmed inside and out with Ram’s new top-of-the-line Laramie Longhorn option package.

Under the hood is a 6.7-liter Cummins inline-six-cylinder oil burner rated at 350 horsepower and 650 pounds-feet of torque. It’s paired with a six-speed Aisin automatic transmission. The gross combined weight rating is 37,500 pounds, according to an information card that was with the truck when it debuted at the Mid-America Truck Show earlier this year.

Say goodbye to squat. All four corners have 19.5-inch Alcoa aluminum 10-lug wheels that are paired with a Kelderman airbag suspension front and rear to manage its high GCWR. The suspension is self-leveling and can manage the air springs independently, kneeling or raising them to provide an optimal rake for the truck.

Who’s the Long-Hauler customer? It’s aimed at power pullers who are looking to step up from a one-ton truck to more capable tow vehicle but think that Class 6 rigs, like a Freightliner SportChassis, are too much truck and too expensive. Think rodeo competitors, farm owners and full-time RVers.

If you want to check it out yourself, the Ram Long-Hauler will be at the Kentucky Derby on May 6 and 7 in Louisville.
