Grave Digger 21

Grave Digger 21 is a Four-link suspension Grave Digger experience truck that is featured at certain Monster Jam events. The truck is transported via a truck trailer that has side doors, allowing people to climb into the truck and watch a video presentation. In order to fit in the trailer, Grave Digger 21 only has two tires, both on the left side of the truck. Grave Digger 21 has never competed in a Monster Jam event.
