I think it's safe to say that the members of Five Finger Death Punch are a driven bunch of guys.

If you've even been to one of their shows, it's also a given that the five of them are probably adrenalin junkies.

But it might surprise fans to know there is a monster truck named Knucklehead.

Over the past weekend, the Knucklehead truck was one of the competitors to compete in the Monster Jam 2015 Finals held in Las Vegas, NV.

Any guesses who the driver was? None other than FFDP guitarist Zoltan Bathory.
