The Caterpillar Motorhome is a custom-built, heavy-duty expedition vehicle designed for overlanders, remote workers, and adventure travelers who require industrial-grade durability and livable comfort. Built on a Cat-certified heavy chassis with military-spec construction, the vehicle targets users who require reliable shelter in harsh environments. Its growing demand reflects the global shift toward rugged, self-sufficient mobile living solutions.
Engine and Performance
The Caterpillar motorhome features a Cat C9.3B inline-6 diesel engine producing 415 hp and 1,695 Nm of torque, paired with an Allison 3000 Series 6-speed automatic transmission. Four-wheel drive with a low-range transfer case handles deep mud, rocky terrain, and steep slopes up to 45 degrees. The engine meets Tier 4 Final emission standards and is designed to operate reliably in temperatures ranging from -40°C to +55°C.
Mileage and Efficiency
The Caterpillar motorhome offers a highway mileage of approximately 4 to 6 km/L, with a 600-liter saddle tank providing a range of 2,400 km on a single fill. A 20-liter auxiliary fuel reserve provides emergency use. The vehicle features a Cat PM800 onboard generator producing 40 kW of power, designed for self-sufficient off-grid operation for up to seven days without an external power connection.
Dimensions and Usability
This motorhome measures 14.2 meters in length, 2.8 meters in width, and 4.1 meters in height, with a GVW of 28,000 kg. Ground clearance is 480 mm, and the approach angle is 38 degrees, making navigation even on difficult terrain a breeze. The interior living area spans 48 square meters and includes robust storage bays, a pull-out workstation, and a dedicated equipment room for heavy outdoor gear.
Variants and Trims
Three primary configurations are available: the base Expedition for standard off-grid travel, the Pro Outpost for long-term remote operations, and the Command Unit for industrial or emergency deployments. Each variant offers a modular interior layout. Optional upgrades include an Arctic insulation package rated up to -50°C, a satellite communications array, solar rooftop panels with an 8 kW capacity, and a medical bay conversion package.
Safety and Technology
Active safety systems include electronic stability control, roll mitigation programming, tyre pressure monitoring on all six axles, and automatic traction control on all driven wheels. The Caterpillar motorhome features a reinforced exoskeleton frame made from 10 mm high-tensile steel. An onboard diagnostics interface connects to Cat’s remote monitoring system, providing real-time engine health tracking and predictive maintenance alerts.
Features and Comfort
Interior features include heavy-duty vinyl and aluminium composite walls, dual-zone climate control that operates independently of the engine, a modular bunk configuration, a stainless-steel galley kitchen, and a 400-litre freshwater tank with onboard filtration.
