Rear locker decisions..

It was constantly searching for a gear.

Fwiw, there is tuning available in the aftermarket for most automatic transmissions and certainly for American makes like Ford, GM, and Ram. Some engine tunes come with transmission tunes. Sure, it costs a bit of money, but can help MPG depending on the tune but also fix the searching issue. Up to you if that's worth dealing with, but the difference can be dramatic.

I don't have an explanation why the tunes from the OEM are so bad other than maybe it has to do with emissions, or maybe they just aren't good at it.

We bought new and the warranty prevented us from doing it. After our second trip out west, we dumped it as soon as we returned. Great comfort in a truck but a hot garbage driving experience with any type of grade.

I’ve been doing a ton of research and you’re the only one I’ve ever heard comment on transmission issues with the 6speed. The 10speed in 2018 was problematic and also had oil consumption issues

Well turns out 2015-2017 has reported issues as well. Pretty much everyone has transmission issues idk what to do here

Reported issues isn't a problem. How much for the fixes? Frequently, there are known fixes or known things to do to keep from having the issues. You'll need to go to brand specific forums to find them.
