2000 Stewart & Stevenson LMTV

Offered by a private seller in Rochester, New York, this 2000 Stewart & Stevenson LMTV pairs a Caterpillar 3116 diesel and Allison automatic transmission with a comprehensively equipped expedition habitat. Showing approximately 12,000 miles, it features a 22.1 kWh heated lithium battery bank, 1,785 watts of solar, 125 gallons of fresh water, and a thoughtfully finished interior with a powered bed lift, full kitchen, and indoor bathroom.

Built for personal use by a mechanical and manufacturing engineer with more than a decade of professional experience across custom vehicles, fabrication, and off-grid systems, this LMTV emphasizes serviceability as much as comfort. The seller reports extensive preventative maintenance and travel testing during approximately 1.5 years of ownership. A custom owner’s manual, engineering operating guide, build documentation, tools, recovery equipment, and numerous spare parts accompany the sale.

• Substantial Off-Grid Electrical Capacity: Four heated Epoch lithium batteries provide a stated 22.1 kWh of storage, supported by a comprehensive Victron 24V electrical system. Three bifacial solar panels deliver 1,785 watts of rated solar capacity, with alternator and shore-power charging providing additional options. A Cerbo GX MK2, GX Touch 70 display, and Victron VRM connectivity support system monitoring.
• Insulated Aluminum Habitat With Multiple Climate Systems: The aluminum M1079 habitat features additional insulation, with seller-reported wall thickness of approximately 4.25 inches and floor and ceiling thickness of approximately 5.75 inches. A Pioneer 9,000 BTU mini-split heat pump provides heating and cooling, supplemented by a separate Velit diesel heater, insulated window covers, and heating pads for the fresh-water tank.
• A Comfortable Interior That Makes the Most of Its Space: A custom electric lift raises the main full-size bed above a six-person dinette, whose powered table lowers to create a second sleeping area. White cabinetry, wood countertops, green upholstery, recessed lighting, and perimeter accent lighting give the living space a warm, finished feel. A full kitchen, indoor shower, dry-flush toilet, and included Starlink Mini round out the accommodations.
• Extensive Mechanical Service and Driveline Upgrades: Reported work includes an engine top-end service approximately 5,000 miles ago, a cooling-system refresh, an upgraded Niehoff alternator, new engine mounts, rebuilt driveshafts, and transmission service. EcoHubs, new Goodyear 395/85R20 tires on rebuilt Hutchinson wheels, and a rebuilt programmable central tire inflation system complement the truck’s expedition configuration.
• Travel Equipment and Documentation Included: The sale includes recovery boards, a kinetic recovery rope, soft shackles, tools, leveling blocks, water-transfer equipment, shore-power accessories, and an extensive collection of spare components. A truck-specific operating guide includes electrical and plumbing diagrams, maintenance information, troubleshooting notes, and buyer handover instructions.

Why This LMTV Expedition Vehicle Stands Out

The appeal of this build goes beyond its military-truck presence. Its systems address the practical demands of extended travel: substantial electrical storage, multiple charging sources, generous water capacity, filtration with UV purification, separate heating options, and accessible system documentation.

Inside, the powered bed and convertible dinette allow the same space to serve as a dining area, lounge, and sleeping quarters. The kitchen includes a propane range and oven, while the enclosed bathroom and outdoor shower connection add flexibility at camp. Outside, locking storage compartments, a cab roof rack, and a screened awning enclosure expand the truck’s storage and living space.

The seller describes this as a tested, turnkey build rather than an untraveled conversion, with hundreds of build and travel photos and videos available to interested buyers. A new project opportunity prompts the sale.
