EPIC ADVENTURE STARTS WITH HEAVY DUTY DNA

FOLLOW US

The New 2024 Sierra Heavy Duty pickup trucks are engineered with the same Heavy Duty DNA–or HDNA–as the people who drive them. GMC Ambassadors Stephanie and Clay from “Life by the Bow” and David Ostapiw of “Ostacruiser” epitomize HDNA–always ready to hit the road, pull their world and fill every day with epic adventures.  

LIFE BY THE BOW

Stephanie and Clay share a passion for boating and a love of the ocean; now the couple create content from their boat trips, fishing and adventures on the water. The ability to confidently tow their 39-foot boat is vital to their goal of making the most out of every single day.

Clay Cowart –

“When the turbo kicks in, you can really feel the torque going to work.”

Stephanie and Clay offered to put the First Ever GMC Sierra HD Denali Ultimate to the test to see how it handled towing and launching their 39-foot fishing boat. The Sierra HD Denali Ultimate is, of course, much more than just a powerful puller. It features a premium interior with comfort and craftsmanship designed to make the whole day a first-class experience from sunrise to sunset. 

Take a look at what Heavy Duty DNA means to them and see how it puts them in the middle of the action.  

POWER TO PULL

Powered by a 6.6L Duramax Turbo Diesel V8 engine with Allison® 10-speed automatic transmission, Sierra HD Denali Ultimate provides plenty of power to handle the boat and trailer. Sierra Heavy Duty offers the most available trailering-assistance technologies in its class, including up to 14 available camera views. Clay and Stephanie found the available hitch view to be a real timesaver when it came to hitching up the trailer.

TAME THE UNTAMED

GMC Off-Road Ambassador David Ostapiw of “Ostacruiser” shares that HDNA, too. He hit the trails in the New 2024 Sierra HD AT4 to see how it performed in the wild backcountry with a trailer loaded with two big Centaur UTVs. The available Duramax Turbo Diesel delivered the needed torque to get the truck and its load moving in the rough terrain. The available exhaust brake helped to control the speed when descending steep grades. 

David Ostapiw –

"The AT4 is luxury on the outside and all business on the inside” 

Go off-road with David Ostapiw and experience Sierra HD AT4’s incredible capability. 

THE REAL DEAL

The Sierra Heavy Duty’s premium interiors, bold styling and large high-resolution screens impressed the Ambassadors. Functional features such as the available World’s First Six-Function MultiProTM Tailgate helped them make their adventures easier. Sierra Heavy Duty is the real deal—with the strength and pulling power to haul heavy loads and the most available trailering-assistance technologies in its class.
