Moving up from the base trim of the 2023 GMC Sierra HD brings us to the SLE and SLT trims. These two trims offer different equipment without heavily focusing on any particular driving element. Unlike the AT4 with its off-road focus and the Denali with its luxury-laden layout, the SLE and SLT trims of the Sierra HD add equipment above the base model. That said, you’ll still want to know which trim to choose.
