This 1997 Stewart & Stevenson M1078 is a former military vehicle that was purchased by the seller approximately four years ago and subsequently converted to an overland-style vehicle with the addition of a camper cabin. The truck is finished in gray and black, and power is from a replacement 6.6-liter turbodiesel inline-six mated to an Allison seven-speed automatic transmission and an all-wheel-drive system. The camper is outfitted with a galley, a dinette that converts to a bed, a workstation, and a wet bath. A retractable awning is positioned on the camp side, and other equipment includes LED lighting, reverse- and side-view cameras, a diesel-fueled air heater, a Senville mini-split air conditioner, and a Dometic refrigerator. Power equipment includes a solar panel array, a lithium battery system, charge controllers, and a 3,000-watt inverter. Work under current ownership is said to have involved replacing the engine, tires, pinion seals, drive shaft u-joints, alternator, and voltage regulator, revising the differential gearing, rebuilding hydraulic cylinders, and changing the oil, coolant, and rear differential fluids. This M1078 camper is now offered in Tennessee with installed component manuals and a clean Arizona title in the seller’s name that lists the truck as a 1997 Stewart & Stevenson Military.

The M1078 is a 2.5-ton Light Medium Tactical Vehicle (LMTV) that is built on a chassis derived from the Austrian Steyr 12M18 truck. This example has been fitted with a camper cabin and refinished in gray and black, with bedliner material applied to the cab. Equipment includes LED lighting, locking front door handles, and a receiver hitch with a seven-pin connector. An 1,880-watt solar panel array with pneumatically operated slide-out panels is mounted on the camper roof, and other features include an entry ladder, a CVT manually operated canopy with two support poles, sliding windows, and utility connections for power and water.

Black 20″ steel wheels wear with 395/85 Goodyear MV/T tires that are said to have been installed under current ownership along with balancing beads. A spare is located on a power-operated boom behind the cab, and stopping power is provided by air–assisted brakes. Work under current ownership reportedly included overhauling the hydraulic pump for the spare tire lift and replacing the rear sway bar bushings. The central tire inflation system operates intermittently.

The bolstered high-back seats and center jump seat are trimmed in gray cloth. Features include a side- and reverse-view camera display, metal window cranks, a center tray, a master power cutoff switch, and textured floor mats.

The two-spoke steering wheel fronts an 80-mph speedometer, push-button transmission controls, and auxiliary gauges for fuel level, oil pressure, coolant temperature, voltage, and front- and rear-brake air pressure. The six-digit odometer shows 32k miles, approximately 25k of which were added under current ownership. True mileage is unknown.

The living quarters have a 75″ ceiling height and are outfitted with woodgrain flooring, white walls with mountain graphics, and overhead lighting as well as storage cabinets, insulation in the walls and ceiling, and blackout curtains. The dinette has bench seating upholstered in gray cloth in addition to a wood table that can be lowered to form a sleeping surface. An adjacent workstation has a desktop, USB power ports, and open shelving. Climate control equipment consists of a Senville mini-split air conditioner, a diesel-fueled air heater, and two Maxxair power-operated ceiling vents.

The galley is located at the front of the cabin and features woodgrain countertops, a double-basin sink, a Duxtop two-burner induction cooktop, 120-volt electrical outlets, and a Dometic dual-zone refrigerator and freezer. The wet bath has a sink, a composting toilet, a tethered shower sprayer, and an overhead exhaust vent with an integrated light. House power equipment includes a 420-Ah lithium battery system, charge controllers, and a 3,000-watt inverter, while the water system has heated lines and tanks, a Bosch 4-gallon electric water heater, a 122-gallon freshwater tank, and a 30-gallon gray water tank.

The replacement 6.6-liter Caterpillar 3116 turbodiesel inline-six is said to have been installed under current ownership following an overhaul. Additional work included replacing the alternator, voltage regulator, fan solenoid, and an oil line as well as changing the oil and coolant. The engine is equipped with a solar trickle charger and a hydronic block heater.

Power is delivered to all four wheels through an Allison seven-speed automatic transmission and a single-speed transfer case. Work under current ownership reportedly involved modifying the differentials with 3.07:1 gearing, replacing the pinion seals and drive shaft u-joints, and balancing the drive shafts.

Owner’s manuals for installed components will accompany the truck.
