Bigfoot is widely called the first monster truck, and it began as Bob Chandler's 1974 Ford F-250. He kept breaking it off road, and local shops did not stock the parts, so he opened a 4x4 shop. In 1981 he drove it over junk cars in a field and filmed the run, and in 1983 more than 68,000 fans packed the Pontiac Silverdome to watch Bigfoot. Bigfoot trucks still tour arenas today.
