Truck King Challenge Winner – Long-Term Test – GMC Sierra 1500

The 2019 GMC Sierra Denali 1500 took the top award at last fall’s Canadian Truck King Challenge. That win, for the GMC half-ton, was a first in the 13-year history of our event. It also came as the Sierra went through a generational update – bringing with it a host of new features, inside and outside the truck. The judges considered everything the new Sierra had to offer, and after two days of intensive road testing, scored it highest among its peers.
