Built by Adrenalin Industries of Richmond, Utah, the Fortress 003 “Duke” is a no-compromise expedition vehicle offered at $350,000, engineered on a rare BAE Titan cab-and-chassis platform. Underneath its aluminum expedition habitat sits a 2012 BAE Titan powered by a Cummins 6.7L turbo diesel producing 325 horsepower and 750 lb-ft of torque, paired with an Allison automatic transmission, upgraded fast axles, and a locking rear differential. Originally derived from military-grade platforms developed by BAE Systems, this limited civilian Titan chassis brings true defense-industry DNA to the overland world. Adrenalin Industries leveraged that foundation to create a fully self-contained, long-range expedition truck designed for global travel, extended off-grid living, and extreme terrain.
- Military Roots, Civilian Rarity: BAE Systems built its reputation producing armored and tactical vehicles for military and government use, later releasing a very limited number of civilian Titan chassis built to those same durability standards. The Fortress Duke starts with that rare heavy-duty foundation before Adrenalin Industries transformed it into a purpose-built expedition platform.
- Commercial-Grade Diesel Power: The Cummins 6.7L turbo diesel delivers 325 hp and 750 lb-ft of torque, routed through a proven Allison automatic transmission for long-haul reliability. Upgraded fast axles allow sustained 70+ mph travel while the locking rear differential provides real off-road traction when the pavement ends.
- Aluminum Habitat, Engineered Not Framed: The 18-foot camper is constructed entirely of aluminum using extruded 6061 structure and bonded .050 exterior panels. With reinforced walk-on roof, insulated walls, ceiling, and floor, and Tern Overland dual-pane windows, this habitat is built for harsh climates, heavy use, and serious longevity.
- A True Off-Grid Living System: With 1,100 watts of roof-mounted solar, 720Ah of lithium battery storage, Victron power management, diesel heat, 12V air conditioning, and full galley and bath systems, the Duke is designed for extended remote living. Every major system is engineered to operate independently of shore power or campground infrastructure.
- Professionally Built, Top to BottomL From the sound-deadened cab and upholstered interior panels to the powered spare-tire lift, garage storage, and commercial-grade electrical architecture, this truck reflects a professional expedition build philosophy. It’s not a concept vehicle, it’s a finished platform designed to cross continents.
The Fortress 003 occupies rare territory in the overland world. Very few expedition trucks begin life on a true military-derived chassis, and even fewer are finished to this level. The BAE Titan provides a drivetrain and structural platform designed for abuse, payload, and longevity. Adrenalin Industries layered on a fully aluminum expedition habitat, modern off-grid systems, and a refined interior capable of supporting months of self-reliant travel. This is not a camper bolted to a truck. It's a purpose-built expedition vehicle engineered as a complete system. For buyers seeking a global overland platform, mobile basecamp, or long-range exploration rig without compromise, the Duke represents a turnkey, professionally executed solution.
