Default 2019 SLT Z31 Charging System

I purchased my truck new in December 2019. When driving I noticed the volt meter moving from 14V down to 11V and back up. Stopped by the dealer the next day and he said that it is supposed to do that. When it notices the battery needs charging, it will go up. In all the years that I have owned chev/gmc vehicles I have never seen one do this while driving down the road. I have seen them fluctuate while idling at a red light with accessories on. Anyone seen this?
