2019 / 2020 Sierra AT4 | Deal Or No Deal? Off Road Edition.

GMC's new AT4 off-road trim includes parts that you can get on your own aftermarket, or on some of their other models as part of various off-road equipment packages. So why get the AT4? Because it's a little less expensive than the parts piecemeal and vs an aftermarket tweak it's fully supported by GMC.
