Grave Digger 20 was a Chevy panel van monster truck driven by Dennis Anderson. This would be Dennis's longest time in a single Digger, running the truck from 2006-2014. The truck debuted in Minneapolis 2005 with a special green ghost body. #20 was similar to design to #19 but with more tubing and a more stable shock package. Dennis would win two more racing championships with Grave Digger 20, one in 2006 and one in 2010. After some time of running the green ghost, the truck went to the original scheme.
