I have a 2021 1500 with the pentastar 3.6 v6 and I have 73k on my truck. I do drive alot for work.i have already had to replace my battery and alternator/generator which has me concerned. The new alternator is doing the exact same thing and when driving at interstate speeds I'm only at 13.1 to 13.3 volts on my gauge cluster. I disconnected electrical components that I had hooked up Ie my light bar and subwoofer. It has not brought the voltage up at all. In fact it keeps dropping under driving load at any speed. I do not understand what the problem is. I have had subs and external lights on all my vehicles and NEVER have had this issue. I am also a 12v telematics professional installer. These issues are seriously making me consider going away from this RAM 1500 all together. Can anybody help me out? 13.3 volts driving on the interstate doesn't seem correct at all. I should be at at least 14
