Dennis Montague Anderson (born October 24, 1960)[1] is an American former professional monster truck driver.

Anderson moved to a newly built Grave Digger 2 in 1989, made with a 1950 Chevrolet panel van body.

TNT began promoting Grave Digger heavily, especially for races on the Tuff Trax syndicated television series and ESPN's Powertrax.

In 1997 he built and debuted Grave Digger 12, which would be inherited by former Carolina Crusher driver Gary Porter in early 2001.

His final event as a competitor took place in Tampa, Florida, at Raymond James Stadium on January 14, 2017, as he was injured and forced to miss the rest of the season.

During Monster Jam's 2018 Season Kickoff Show on September 18, 2017, Anderson announced his retirement from the sport.

In late 1991 he broke his kneecap when he hit a wall at the Rosemont Horizon in Chicago, forcing him to sit out the 1992 winter season.

He recovered and beat Jack Willman Jr. in Taurus at Carter Finley Stadium in Raleigh, North Carolina.

A nose-dive, AKA the lawn dart, at the Louisiana Superdome in New Orleans in 1999 aggravated the injury and caused Anderson to miss several shows over the next couple of years.

A lesser-known injury happened during the summer of 2006 in a non-monster truck accident when Anderson injured his wrist.

He also suffered a shoulder injury at the Metrodome in late 2006, in which his son Adam Anderson drove Grave Digger at shows in early 2007 until The Monster Jam World Finals 8.
