Kenny Bruner’s ‘06 Dodge Ram is unquestionably over-the-top. From the bright paint and tilt front end to the big-horsepower engine and partial tube chassis, Kenny built his truck with one purpose in mind: to compete in the Ultimate Callout Challenge.
The ’97 F-250 wasn’t always a sleeper, though. When Indiviglio picked up the one-owner, 119,000-mile Super Cab back in 2010 it was far from the 580hp truck it would eventually become, but it was still a pretty cool truck to roll into high school with.
