Keystone Beer was a 1989 Chevrolet Silverado monster truck owned and driven by Dan Patrick out of Circleville, Ohio from 1990-1993. This truck was sponsored by the beer company of the same name, and was the same truck that ran as Samson, Coors Extra Gold, and American Gladiators.
The truck has also been referred to as Keystone Krusher, which is likely confused with the other truck of the same name, and Keystone Beer Cruncher, however these were never official names used for the truck.
