- The truck spawned from the combination of two cancelled trucks, being the dog theme of Beware of the Junkyard Dog, and the supposed Mercury body of Hulk in 2003. The original bottom clip where the latter's teeth would have been set in (where the tongue is) can be seen in images of the truck at its debut show.
- The truck has been driven at least once by approximately 30 drivers throughout the truck's career.
- When the Grave Digger chassis ran the old body, the body was bolted on in a titled fashion to fit the rollcage.
