In the 1980s and ‘90s, Californian Bran Ferren was the president for research and technology at Walt Disney Imagineering. The job took him to remote places scouting for film locations. Getting there often required adapting vehicles for the purpose. This led to an interest in off-road expedition vehicles. In 2001, Ferren began building his own expedition vehicle, based on the Mercedes-Benz Unimog. He called it the MaxiMog. Ferren, now 64, has come up with the ultimate expedition vehicle, a high-tech truck and trailer he has named the KiraVan after his daughter Kira, aged 7.
