The military uses Stewart & Stevenson 4×4 and 6×6 trucks to do a lot of its heavy lifting and transport. These trucks are part of the FMTV (Family of Medium Tactical Vehicles). These trucks are generally rated to carry either 2.5 or 5 U.S. tons of payload, and transport the load over rough terrain.

Acela Truck company resets and refurbishes these big trucks for civilian use. They call the finished trucks the Monterra 4×4 and Monterra 6×6.

These trucks are running on 46-inch tall off-road tires. They offer 22 inches of ground clearance. Power comes from a 7.2-liter Caterpillar turbo-diesel engine. The rating is 330 horsepower. These trucks are off-road ready with full all-wheel-drive capability and a Central Tire Inflation System (CTIS).

Acela performs a 300-point inspection on each truck. Their reset process replaces 600 parts with OEM-certified parts and components. Once the trucks are taken apart, rebuilt with new parts, and painted – they also go through performance testing and final evaluation on and off the road.

These trucks can be re-geared to allow them to reach a top speed of approximately 74 MPH.

These Acela 4×4 and 6×6 chassis can then be outfitted as an overland expedition vehicle, a high water rescue, a construction truck, and much more. Speaking of high water, there is an optional package that allows the trucks a 50-inch water fording capability.

A fully-built Acela 4×4 chassis starts at $100,000. The 6×6 truck chassis starts at $110,000.
