2000s: Hummer and M.O.D Days
In 2000 Kreg made Dragon Slayer the only Hummer monster truck in the world, and became well known across the USHRA and through the M.O.D tour which he became a champion. In 2008 Kreg sold Dragon Slayer after he joined 2Xtreme Racing. The truck then became Western Renegade. The last Dragon Slayer competes today as Buckshot.
In 2003, for the Hotwheels release of Dragon Slayer featured an interesting feature. Some of the toys read "Kreg Christensen" on the door as the driver, while the other half read "Dj Johnson" (Most Likely BJ Johnson).
