The CP4 issue has been way overblown in my opinion. Call your local dealer and ask them how many they have had to replace vs how many trucks they have sold. Also all HO trucks built after July 2020 have a revised symmetrical CP4 pump that may be a fix for those CP4 problems that did arise.
Probably, but it's a known issue that can be really significant. It was certainly a factor when I picked a Ram back in 2015. The current Duramax doesn't have one. They're all good trucks, I'd personally lean towards the one without the known issue. Buying used that might make me lean Ram, new probably Duramax.
I totally agree; if I were shopping for a new diesel truck today it would almost certainly be a GM.
