In Summary

The 2019 Sierra 2500 HD Denali is a stylish, tech-forward heavy-duty truck built for those who tow often. The diesel model shines in capability and towing ease, while the gas variant is more budget-friendly. Both deliver luxury Denali trim vibes—but expect a stiffer ride and consider towing needs before deciding.
