TURTLE IV (1992-2001)

WITH a 36,000-mile expedition around the Northern Hemisphere in the works, the Turtle IV, a Ford F-350 turbo-diesel, included mods specifically designed to withstand -60°C conditions. The 7.3-litre Navistar diesel, Four Wheel Camper and cab were upfitted with engine and fuel preheaters, diesel space-heaters, high-tech insulation and a trailer to haul fuel. The Turtle IV had ARB lockers, Rancho suspensions, BFG tyres, a Mile Marker winch, National Springs, Optima batteries, and a K&N air filter and intake system. The Turtle IV completed the wintery expedition before being retired in 2001.
