This 1998 LMTV Was Rebuilt Into A Go-Anywhere Off-Grid Expedition Truck

Military trucks were built to haul gear, handle abuse, and keep moving in places most civilian vehicles would rather avoid. That foundation makes them a natural fit for expedition use, and this 1998 M1078 Light Medium Tactical Vehicle (LMTV) from Hunter RMV is a strong example of what can happen when one is reworked for life beyond the pavement.

The build starts with an LMTV chassis originally designed for military transport duty, then layers in the systems, storage, and living space needed for extended backcountry travel. What comes out the other side is not just a converted service truck, but a fully outfitted overland rig designed to cover ground and stay off-grid in comfort.

Off-Grid Capability Comes First

A big part of this truck’s appeal is how well it is set up for long stays away from hookups and established campsites. The water system includes a 100-gallon fresh-water supply and a 40-gallon gray-water tank, providing the rig with the capacity needed for extended remote travel.

Its electrical system is equally substantial. A Victron-managed setup works with 1,800 amp-hours of lithium battery storage and 1,000 watts of solar, helping support the truck’s onboard systems without relying on shore power.

That self-contained approach carries through the rest of the living space. The habitation box includes a propane oven, a refrigerator and freezer combination, an additional freezer, a dishwasher, a washer and dryer, and a Wrappon Trekker electric toilet. Indoor and outdoor showers add another level of flexibility, whether the truck is parked at a remote campsite or covered in trail dust and mud after a long day.

A Military Chassis With A New Mission

For this project, the customer supplied the 1998 M1078 chassis, which was then refurbished and reworked in-house. That process included mechanical freshening, updated paint, and a complete redesign of the living module.

The custom 18-foot habitation box gives the build much of its personality. Rather than going with a generic finish, the exterior design was based on a topographical map file tied to the customer’s home terrain. It is a detail that gives the truck a more personal identity while still fitting the rugged nature of the platform.

Diesel Power Backs The Build

Power comes from a Caterpillar 3116 inline-six diesel rated at 225 horsepower and about 520 lb-ft of torque. Behind it is an Allison MD 3070 PT electronically controlled seven-speed automatic transmission, a pairing known for dependable performance in heavy-duty use.

The fuel capacity is listed at 116 gallons, giving the truck an estimated driving range of about 800 miles. For an expedition vehicle expected to venture far from major roads or fuel stops, that kind of range can make a major difference.

The truck also uses a Central Tire Inflation System, allowing tire pressure to be adjusted from the cab as terrain conditions change. That can be a major advantage when moving from pavement to soft sand, snow, or loose dirt, where the right tire pressure can improve both traction and ride quality.

Why The LMTV Platform Works So Well

The M1078 remains a compelling base for an overland conversion because much of the hard work is already done before the camper box is added. The platform is known for its 2.5-ton payload capacity, 4×4 drivetrain, and strong off-road performance. Originally built for troop and cargo transport in demanding conditions, it offers the kind of durability and capability many expedition travelers seek.

High ground clearance and 45-inch tires only add to that appeal. Instead of adapting a lighter-duty truck for hard travel, a build like this starts with a platform engineered from the ground up to carry weight and handle rough terrain.

More Comfortable Than Its Origins Suggest

While the LMTV’s military roots are obvious, the interior upgrades move this truck far from bare-bones tactical transport. In the cab, the standard seating was replaced with Scheel-Mann leather seats, making long travel days far more comfortable for both driver and passengers.

Inside the living area, gray-painted solid-wood cabinetry and butcher-block countertops strike a balance between durability and warmth. The overall finish gives the truck a practical residential feel without losing sight of its intended use as a heavy-duty expedition vehicle.

A Specialized Build For A Specialized Buyer

Since 2015, the company behind the build—Hunter RMV—has focused on transforming retired military chassis into expedition vehicles Hunter RMV—has focused on transforming retired military chassis into expedition vehicles for serious remote travel. It first drew attention with an M939 6×6-based prototype called “The Beast,” and has since expanded into LMTV-based builds and other military platforms.

These trucks sit in a niche corner of the market. With builds typically running from $300,000 to $400,000 before the cost of the chassis, they are aimed at buyers who want something far beyond conventional campers or RVs. The value lies in a combination of heavy-duty construction, customization, long-range capability, and the unmistakable presence that comes with a repurposed military platform.

This M1078 build shows how well that formula can work. What started as a military workhorse is now a long-range off-road rig with the equipment to travel comfortably into the deep remote.
