This 2002 Freightliner FL60 4x4, originally an ambulance, has been extensively converted into an overland-style camper with 134k miles. It features a custom habitat with a kitchenette, shower, toilet, and a sophisticated electrical system including dual Tesla Model S battery packs, a 1,200-watt rooftop solar system, and radiant in-floor heating. Power comes from a Cummins 8.3-liter turbodiesel inline-six paired with an Allison five-speed automatic transmission and a dual-range transfer case.
