For those in the off-grid community, EarthRoamer expedition vehicles sit atop the food chain. Built to conquer the roughest terrain, sustain you for weeks in the backcountry, and turn heads when rolling into town, we’d like to introduce you to the 2023 EarthRoamer SX-005. This diesel-powered dream rig has just 18,823 miles on the clock and a used pricetag of $1,110,000 per EarthRoamer’s PreRoamed website section, where you can browse a healthy selection of used EarthRoamers. The epitome of a mobile fortress, the EarthRoamer SX is desired by all, but obtainable for few.

Chassis, Powertrain, And Suspension: A Truck-Based Rig

At the heart of the SX-005 is a Chevrolet Silverado 6500HD chassis. This heavy-duty commercial-grade platform supersizes the consumer-grade pickup truck platform—with the added benefits of an air horn. Under the hood, the Duramax 6.6L turbodiesel V8 delivers uncompromising power and torque, while the Allison six-speed transmission ensures smooth power delivery.

The off-road suspension has been tailored specifically for EarthRoamer vehicles, combining components like custom air ride suspension, King off-road remote reservoir shocks, anti-sway bars, and 43-inch Goodyear tires on military-grade beadlock wheels for a smooth, controlled ride. This suspension system allows for easy leveling at the camp site.

EarthRoamer’s proprietary rear pivot camper mounting system lets the chassis flex naturally off-road without torqueing the vacuum-infused carbon fiber monocoque camper body—a necessary feature when navigating rugged terrain. Add to that a 100-gallon dual-fill fuel system and you’re looking at a serious range before needing to refuel, making the SX-005 a true long-range expedition machine.

Self-Sufficient Living

This EarthRoamer is a fully self-contained, off-grid habitat. The EarthRoamer SX-005 comes equipped with an 18-kWh lithium-ion battery bank, powered by a 1,600-watt solar array and backed up by an auto-start engine charging system that automatically starts the engine when the batteries are low. Combined with 120 gallons of fresh water and a 55-gallon grey water tank, you can stay unplugged for a while—while still run air conditioning, lighting, entertainment systems, and kitchen appliances without compromise.

The entire electrical system is housed within a marine-grade digital monitoring network, offering full system diagnostics and control at the touch of a screen. The SX also features Starlink internet and a 5G cellular router, keeping you connected in the most remote corners of the continent.

A Cabin-Like Interior

Step inside, and the SX-005 blends off-road function with high-end finishes and maximum coziness. The Mount Shavano floorplan features a spacious dining area that converts to a California King bed, plus an overhead bunk for extra sleeping area. The bathroom is a fully enclosed dry bath with a walk-in shower, high-end fixtures, and dual 5-gallon toilet cassettes. Vaulted, soft-touch ceilings and premium materials like Russet (Cherry Knotty Alder), leather, maple hardwood, stainless steel, granite, quartz, and machined metal give it a warm, cabin-like feel.

It comes fully loaded with upgraded features like a drop-down TV package, washer/dryer combo, Jura Ena 8 coffee station, wine fridge, central vacuum system, and even under-mattress gun storage. EarthRoamer dinnerware, glasses, mugs, and silverware travel nicely in built-in custom storage organizers.

Built For Exploration And Recovery

The SX-005 is ready for whatever the trail throws its way, with Warn 16,500-pound front and rear winches, a tire inflation/deflation system, and front, rooftop, and bumper cameras. You also get a FLIR infrared camera, off-road light package with amber LEDs and rock lights, and a GOST security system for peace of mind.

Outside, the rig features a Blackstone exterior kitchen, automatic awning, electric spare tire winch, and heavy-duty bumpers. Every inch of this vehicle screams capability.

A Pricey Mobile Fortress

At $1,110,000, we get that the diesel EarthRoamer SX-005 isn’t just a camper—it’s a mobile fortress. For those who live and breathe remote travel, off-grid freedom, and a check-all-boxes lifestyle, it represents the pinnacle of expedition vehicles. With commercial-grade underpinnings, advanced off-grid systems, and true home-level comfort, the SX-005 is a family heirloom that will take you farther, longer, and in more style than pretty much anything else on the road.
