Sorry for a possibly stupid comment...
Is it possible to run just one alternator? I’m thinking a different belt just for the single setup. It seems you said the load from them made a change.
Or since they both turn freely possibly just disconnect (and tape up) the wiring from them one at a time to see if there’s a change. Double alts can be a good thing but they could also be hiding an issue with one of them.
Just a thought and it’s free to try the disconnect.

@jstihl any updates on this thread for your idle surge and alternator P1105 issue?

Recently an FTE'r was having some stumbling and stalling issues when the truck was coming to stop. While replacing his IPR and ICP again, he noticed the EOT sensor harness side was broken. He ziptied it together and all has been well since.
Another FTE'r had a stumble at idle only when warm. His BIL bought the truck and found one of the injector cups was leaking and possibly causing the ignition sequence to be interrupted by the coolant. Also, his EOT was providing erroneous readings via FORScan and was replaced.
I am not saying your issue is any of these noted above, but just some details observed over the past few months from other FTE'rs.

Yes, still have it. I've procrastinated on working on it again, since it seems to put out most of the time.
