A former construction worker from the St. Louis, Missouri area, Chandler began building the first Bigfoot in 1975, using the Chandler family's 1974 F-250 four-wheel drive and found that automotive shops in the Midwest generally did not carry the parts needed to repair his frequently-wrecked 4×4. To remedy this problem, Chandler and his wife Marilyn, along with friend Jim Kramer, opened a shop called Midwest Four Wheel Drive and Performance Center in Ferguson, Missouri. The shop moved to Hazelwood, Missouri in 1984, which remained as Bigfoot's headquarters until 2015 when the headquarters was relocated to Pacific, Missouri.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.In 1979, Chandler started making appearances at truck and tractor pulls, as well as car shows, with his newly christened "Bigfoot" to show off the truck's capabilities as well as to promote his shop.
