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.

The sixth generation of the Ford F-Series, also known as the "dentside Ford" to enthusiasts, is a line of pickup trucks and medium-duty commercial trucks that were produced by Ford Motor Company from the 1973 to 1979 model years. Produced by Ford in North America, Argentina, and Australia, this is the third and final generation of trucks derived from the 1965 Ford F-Series.
