Bigfoot is a monster truck. The original Bigfoot began as a 1974 Ford F-250 pickup that was modified by its owner Bob Chandler beginning in 1975. By 1979, the modifications were so extensive, the truck came to be regarded as the first 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.

A monster truck is a specialized off-road vehicle with a heavy duty suspension, four-wheel steering, large-displacement V8 engines and oversized tires constructed for competition and entertainment uses. Originally created by modifying stock pickup trucks and sport utility vehicles (SUVs), they have evolved into purpose-built vehicles with tube-frame chassis and fiberglass bodies rather than metal. A competition monster truck is typically 12 feet (3.7 m) tall, and equipped with 66-inch (1.7 m) off-road tires.
