The GMC Sierra 3500HD Denali by Rolling Big Power and Keaton Hoskins is a one-off truck that showcases custom features designed for disabled people. Unveiled at the 2019 SEMA Show, this truck was created by Rolling Big Power, an industry leading manufacturer of aftermarket parts and Keaton The Muscle Hoskins from TV's Diesel Brothers. It is based on the older, third-generation Sierra 3500HD Denali. The truck was built for Jonathan Barber, who was involved in a coal-mining accident in 2017 that left him paralyzed from the chest down. Fitted with a 14-inch lift suspension, this bespoke Denali truck also features a gullwing door, hydraulic chair lift, and twist-handle controls for throttle and brakes, all designed to make life easier for its disabled driver. It's fancy on the outside and practical on the inside, but it's also special enough to draw a lot of onlookers at the SEMA Show or other truck-specific events. In other words, it's a handicap-accessible show rig that we don't get to see too often.
