So while on a road trip with our 5er, I had a rider in the back periodically let me know what the volt meter read. During the trip it seemed to climb from around 14v to about 14.25. The next reading was 13.8 with no electrical changes in the trailer. I also noticed on my digital readout in the cab that the commanded alternator voltage went from 15 to 14.9. I know that's not a big jump, but it confused me a bit until I thought about the possibility of Dodge writing in a smart charging program for the trailer lead. Seams totally possible to me and never considered auto makers might do this...
That's almost "normal" on my cheap device that plugs into power port. Although mine most I've seen is 14.75 max. Flip your a/c on and off couple times and watch read out. Surprised me.
