So just to post a final update....
I removed everything I installed, took it back to the dealer I bought it from and after about a week they were able to fix it completely under warranty.
Somehow the factory alarm system (an option I don't even have!!) became enabled and was causing the battery...
That's what I'm going to have to do. They quoted me $400 to "remove" my wiring and then diagnose the problem. This was the closet dealer to me, I'm hoping the dealership I bought it from will be more willing to help.
Did you get any resolution to this? My situation is very similar. 2023 Badlands. The dealer said they can't do anything because of the hood deflector lights I have wired into an upfitter switch (which I've had for months before this issue started.)
After I charge the battery you can hear a relay...
