I have a 2013 Chevy Silverado Extended Cab with 5.3 engine with 77000 miles on it. I purchase this vehicle in April 2019. I have driven it about 2000 miles and pulled my 23 trailer with no problems. ...
Yup, I believe that GM uses the acronym "RCS" for Regulated Charge System" or somehthing along those lines. My 2006 Sierra 3500 does pretty much the same thing except I don't think that I have ever seen it as high as you are noting. I have seen it hit 15V under heavy operating load.
Cheers!
Mike
