In 2022, Cappello joined Front Row Motorsports as an engineer for its NASCAR Camping World Truck Series team in the No. 38 Ford driven by Zane Smith, who went on to win the championship at Phoenix Raceway.[2] He remained with the team the following year, this time serving as the lead engineer, where they finished seventh in the final points standings. It was also during this year that he returned to the now ARCA Menards Series West at the Las Vegas Motor Speedway Bullring, driving the No. 88 Ford for Naake-Klauer Motorsports.[3] After setting the fastest time in the lone practice session,[4] he qualified in the eighth position,[5] and went on to win the race after Sean Hingorani suffered brake issues whilst leading and surviving two late-race restarts. This was his first career win in two starts in the series.[6][7][8]
In 2024, Cappello was announced as the crew chief the No. 38 for Front Row Motorsports in the Truck Series for rookie driver Layne Riggs.[9] At Homestead, NASCAR imposed an L1 penalty on the No. 38, docked the team 10 driver and owner points, and suspended Cappello for the Martinsville race after the truck was found to be underweight during pre-race inspection.[10][11]
