"Underneath" Motor, transmission is probably still the same. I'm guessing they've updated the wiring harness, transmission and infotainment which is what most people had problems with.

Outside of maybe the lugnuts, I don’t think there’s a single shared part number between a ‘19 and a ‘21+. It’s completely different.

Exactly!! Jeeze...two totally different generations and trucks. 2015-2020. and 2021-present...and totally different issues known to each generation.
