Bigfoot, introduced in 1979, is regarded as the original monster truck. Other trucks with the name “Bigfoot” have been introduced in the years since, and it remains a well-known monster truck moniker in the United States. Bigfoot 4×4, Inc. is owned and operated by its creator, Bob Chandler.
The truck’s first attention-grabbing modification came when Chandler heard of an idea proposed to the US Army of making steering capable on both axles of their four-wheeled vehicles, so that in the event of breakage in the front axle, it could simply be switched with the rear axle and held straight with a pin so that the vehicle could resume regular use with steering.

Chandler decided to test that theory on his truck, but in addition would actually enable steering on the rear axle. The end result was an innovation in automotive technology – the “4×4×4,” or a vehicle with four wheels, four-wheel-drive, and four-wheel-steering.
