Weird Voltage reading

Guys I need your quick...
So I left NY yesterday and I'm in Orlando now.
On the way here and as I'm typing this thread. My voltage shows very low.
Only difference we have done is the demand on all the phone, laptop and IPad hook up to the ports.
Is this normal?
If I turn off the truck and restart it goes back to normal.
The other thing is we have driving the truck nonstop for 18 hours.

Probably the "fuel saving" mode of the charging system. The NNBS has it too.

Looks like back to normal from a good rest.

Drove down to Key West a couple of months ago. A lot of Leos were out on US 1..FHP and Monroe Sheriff were all over the place.

I had been pretty good with the speed limit. Taking advantage on the 75 mph

It was like 104 degrees. Crazy!

Anywhere in that range from 14 is normal. that horizontal white line that goes thru 14 to the two verticle lines say at 13-15 but prob more 12-16 is all normal.... def rvc.... alt shuts off and turns back on when batt falls below 12v-ish or so. Tow/haul made is supposed to turn that off so it should read in the midd somewhere and some other combinations turn RVC off also
