In 2021, Huff was scheduled to drive part-time in the Truck Series for CMI Motorsports in their No. 83 truck beginning at the season-opener at Daytona. When it was announced that Tim Viens would instead be driving the No. 83 truck in that race, CMI revealed in a tweet that Huff would instead drive for them in other races. However, Huff did not end up running any races for the team in 2021. Huff started his own ARCA team that year, Huff Racing, with himself driving the No. 36 car in the races at Talladega and Pocono. He and his team also entered the races at Daytona and Talladega in 2022. Huff returned to the Truck Series for the spring race at Kansas in 2022, driving the No. 46 for G2G Racing, which looked very similar to the truck at Darlington which Brennan Poole drove.
