We’ve previously covered the baseline offerings of the 2020 GMC Sierra 2500HD model. However, we wanted to bring some special attention to the AT4 off-road focused variation of this already incredibly capable Heavy Duty pickup truck model. The 2020 GMC Sierra 2500HD AT4 combines the wonderful specs and features of the standard Sierra 2500 Heavy Duty model with an illustrious off-road identity and plenty of additional performance features and exterior and interior aesthetic accents.
