The truck was created by SFX and PACE Motorsports, the then-parents of Monster Jam, in 2001, as a spin-off of the Bulldozer design for driver Lupe Soza, who had previously owned and driven Warrior from the 1980s.

Although its racing results were disappointing, Soza's freestyle run was lauded as exceptional and he finished second overall.

In 2004, Soza driving El Toro Loco was a Monster Jam World Finals freestyle co-champion with Madusa driven by Debrah Miceli, and Maximum Destruction driven by Tom Meents, all tied with a score of 31.

By 2013, with the truck being one of the top merchandise sellers on the series, multiple El Toro Loco trucks have been run simultaneously on separate tours, with a variety of drivers, including notably Marc McDonald, who succeeded Soza as the lead driver, and Chuck Werner.
