Video Tour of the 2025 Host Mammoth 11.6 Truck Camper

The Elevation Off Grid (EOG) Rig took first place at the just completed 2024 Overland Expo Mountain West in Loveland, Colorado. For this build, of course, it all starts with EOG Ford F-550 Black Edition with 41-inch super singles and a LiquidSpring Suspension, outfitted with a Bowen Customs truck bed with loads of storage. Topping it all off is a luxurious Host Mammoth 11.6 triple-slide truck camper—the largest slide-in truck camper in today’s market—equipped with an “off-grid extreme” package consisting of a 1,200 amp hour off-grid battery system, 800 watts of solar, and a 3,000 watt inverter. Both the truck and the custom truck bed are painted a matching “Nardo Grey,” a custom color not offered by Ford.

When it comes to luxury camping, it’s hard to beat the Host Mammoth 11.6. Inside, you’ll find a “host” of amenities and high-end touches not found in your typical truck camper. These include a leather sofa, an electric fireplace, a mantel with a 32-inch flat-screen TV, a huge dry bath with a porcelain toilet and a large shower, a two-door 8 cubic foot refrigerator, molded counter tops, and a massive, four-door pantry in the kitchen. With an overall length of 19 feet 3 inches, and a floor length of 11 feet 6 inches, it’s one of the largest slide-in truck campers in the industry. Part of what makes the Mammoth so big is that it features three slide-outs. These slide-outs create an enormous amount of living space—180 square feet to be exact—the equivalent of what you’ll find in a large motorhome. New for 2025, are the white countertops which contrast well with the Host’s interior finishes.
