POWERTRAIN
The M1083A is powered by a Caterpillar CAT C7 inline six-cylinder turbodiesel, good for 300 horsepower and 925 lb-ft of torque between 1,800 and 2,200 rpm. This 1200-pound engine features direct injection, HEUI injection, ACERT (Advanced Cat Emissions Reduction Technology) , and an ADEM A4 Electronic Control Unit. The seller reports that the EGT sensor on the turbocharger has been replaced, along with all the filters. The bottom of the cab has been soundproofed with Dynamat to reduce engine noise. The cab tilts forward with a power-operated mechanism. The Allison seven-speed automatic transmission provides power to all six wheels at all times. The vehicle has an on-road mode where 70 percent of the available torque is directed to the rear wheels, with 30 percent up front. The off-road mode splits torque evenly between the front wheels and the two sets of rear wheels.
EXTERIOR
This M1083A is primarily painted camouflage, and it shows well with no obvious damage to the exterior sheetmetal visible in the photos. The Gichner S-280 Shelter is painted olive drab and was professionally painted. The shelter features custom fabricated Marine windows with heavy-gauge aluminum framing for the front and rear of the unit. The seller reports that all of the exterior lighting is functional, with the front lights having been converted to LED. Modifications include a propane water heater, a gray-water tank, an extra 50-gallon fuel tank with a 12-volt DC pump, two 5-gallon propane tanks for cooking, and the water heater. At the rear, the truck has twin tow shackles and winch line rollers, ladder storage, a pintle hook, and a Front Runner roof rack over the cab. The mirrors are heated and have remote electrical operation.
INTERIOR
The driver's seat is a custom air ride unit with upholstery that doesn’t match the center or passenger seats. The upholstery on the driver’s seat is a gray tweed cloth, while the two other seats are olive drab canvas. The cab features an array of gauges that are reportedly all functional, which glow green at night when the exterior lights are on. The center of the dash is dominated by switches for the air brakes, an air-conditioning module, and controls for the PTO and winch operation. The cab has a round center door in the roof to access the outside if the roof rack isn’t in place. Storage includes areas behind the seat and a rifle rack. The shelter in the bed is custom built inside with a refrigerator, a sink, a bed with a Tempurpedic mattress custom fit to the 52-inch by 80-inch space, a portable chemical toilet, a small standup shower, and a cooktop with a stainless-steel backsplash. The custom-built Moduline cabinets have a Posi-Lock system that keeps the drawers and doors closed when the truck is operating off-road.
CHASSIS
Though built in Texas, these trucks were derived from the Steyr 12 M 18 truck, but substantially modified for U.S. military use, which required 50-percent U.S.-based content. Classed as Medium Tactical Vehicles, they’re rated for 5 tons of payload. These trucks were the first to pass the U.S. Army’s 22-year accelerated corrosion test, and the cold-formed C-section high-grade 758 MPa steel chassis underneath shows no signs of rust or other damage. The truck has power-assisted steering, which the seller says works well, with no leaks from the system. The suspension was reportedly serviced one year ago, and the seller notes that all of the components are in “great” condition. The seller reports that the air brakes are fully functional and work well. The military wheels are equipped with Michelin X regrooveable radials, sized 395/85R20, which the seller estimates have traveled about 5,000 miles. The wheels have a central tire inflation system allowing inflation or deflation from the cab.
