Now this is what we call a handicap-accessible vehicle!

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.

Already a massive truck in standard form, this GMC Sierra 3500HD looks even more menacing with updates from Rolling Power and Keaton Hoskins.

It's mostly the 14-inch lift that gives it an imposing stance, but the massive Fusion front bumper helps turn it into a vehicle worthy of a Mad Max film.

On top of the grille we can see a custom piece with big silver studs on the frame, a design that adds to the imposing look. The standard headlamps were replaced with LED lights from Primo Dynamics.

The profile is essentially identical to the standard model, but the wheels make the truck look significantly different. The Rolling Big Power 12R Apex wheels measure a whopping 24 inches and feature True Spike lug nuts, while the Repulsor tires, also made by Rolling Big Power, measure 40 inches. The truck also features an RBP fuel door and Stealth Power running boards. The latter allow easier entry in the rear seats and the front passenger compartment.

As for the disabled driver, he can enter the truck effortlessly thanks to a hydraulic chair lift designed by All Terrain Conversions.

Finally, the bed features a Leer shell for secure storage space that can hold a wheelchair and additional gear.

All told, this modified truck is a fine example of how a vehicle for disabled people should be designed. Minus the big 14-inch lift kit, of course, which was added simply because the owner is a fan of high-riding trucks.

There are no photos of the interior to run buy, but as we mentioned in the previous section, the driver’s compartment features a hydraulic chair lift.

The disabled driver can get out of his wheelchair and climb into a special chair that's automatically lifted into the cabin.

Using pedals is also an issue for people who are paralyzed from the chest down, so Rolling Big Power added hand controls with a twist handle for throttle and brake control.

The lack of additional info suggests that there are no important modifications to talk about, so this truck is probably a standard Denali inside the cabin. The Denali is the range-topping trim in the Sierra range, so it’s fitted with a wide range of premium features and technologies.

  • 14-inch lift

  • Wehrli Custom transmission
  • SunCoast torque converter
  • HP tune
  • Standard engine
  • Gasoline or diesel

When it comes to drivetrain upgrades, this GMC Sierra 3500HD is obviously far from standard.

The 14-inch lift keeps the truck high above the ground, while the custom King shocks ensure it stays there in rough terrain.

Rolling Big Power also mentions updates like a Wehrli Custom transmission, a billet SunCoast torque converter, and an HP tune, but otherwise, it keeps engine details in the vault. This probably means that the mill remains mostly unchanged compared to the standard truck.

The old, third-generation 3500HD was available with two engines and we don’t know which one is under the hood.

Engine options include a 6.0-liter V-8 gasoline engine and a 6.6-liter Duramax V-8 diesel.

The gas unit cranks out 360 horsepower and 380 pound-feet of torque, while the oil burner generates 445 horses and a whopping 910 pound-feet of twist. No matter the engine, this truck is as capable as they get, despite the old gas choice being notably less powerful than the newer, 6.6-liter V-8.

Final Thoughts

Any truck that rides on a 14-inch lift suspension is pretty impressive, but the big highlight here is that Rolling Big Power turned this hauler into a disabled-accessible vehicle. This kind of option should be more readily available for all sorts of vehicles and automakers should cooperate with aftermarket builders to offer options to disabled drivers, whether they’re victims of unfortunate accidents or veterans. Rolling Big Power is setting a good example here.
