I much prefer the Sierra over the Silverado, but it looks like I may be forced into the Chevrolet because of option issues. I want a 2019 with the 3.42 rear end and the 6.2 engine with at least the SLT trim and HUD display. However, it turns out you absolutely cannot get the HUD in a SLT. It requires Denali or AT-4. That would be ok with me, but you can’t get the 3.42 rear end in the Denali or AT-4. So I’m screwed there. In the Chevrolet Silverado you can get all the above in a fully dressed LTZ. Why does GMC make it so hard to option a truck? There appear to be cool new colors in the GMC that aren’t on the Chevy. I wish someone at GM could explain the logic.
