Hah you got it, I used to be a “Chevy guy” when it came to domestic trucks but this was the truck that finally made me say enough, it’s riddled with embarrassing faults and bad design decisions in every system. The Ford truck we also have is an example of new tech that works well and the Chevy just can’t compare.
