They don’t get much bigger, have more range or more pulling power than the Ram Long-Hauler Concept truck, the press release starts. No one would doubt them, just look at this thing!

On display at selected events across America, the Ram Long-Hauler is based on a Class 5 Ram 5500 Crew Cab. They then converted to a Mega Cab passenger compartment, added an 8-foot box and upped the range between refueling stops with a mid-ship fuel tank. Combined with a second frame-mounted tank and a third, optional, bed-mounted auxiliary tank, total fuel capacity is 643.52 litres!

This monster is 24 feet or 7.3 metres long, with the wheelbase along accounting for 5 metres. With a 37,500 Gross Combined Weight Rating (GCWR), the Long-Hauler can probably tow your house away.

Under the hood is an inline six-cylinder 6.7L “High Output Cummins Turbo Diesel” rated at 1,085 Nm. It’s mated to a six-speed Aisin automatic with four-wheel-drive transfer case coupled to a 4.88 Dana 110 axle with dual rear wheels.
