Oh boy, this thread is going nowhere. All I know is they all had there issues at one point or another. I will put long term reliability first when looking for a truck at the time I am looking, could be Chevy today and Ram or Ford tomorrow. Gm has been a good to me on my last 3 trucks although the new 2020 hds don't have the visual appeal. That's why I'm leaning towards a 2019 GMC or Chevy HD plus they don't have the potentially bad CP4 fuel pumps that Ram and Ford I believe are using. 2019 GM if I were buying today.
