My Idash reads 14.3-14.7 volts when running, has been that was since about 20k miles on my original batteries in my 21'.I have just about 30,000 miles now....worried Ill be replacing them soon with all the horror stories about crappy batteries soon but they load tested good when I checked them in August.
my pax side seems to go out first then that pulls the drivers side into the gutter.
I added a thick battery cable from pax side battery neg to drivers side battery negative . That in itself gave me more cranking amps so also hoping charging will stay balanced. Bought a state of charge test or to monitor.
pax side battery ground was tested, cleaned, reinstalled but nothing obvious. There has been a lot of pax side battery failures lately.
In my experience, the negative cable should be grounded to the frame, for sure, but also to the body (for all electronic componentry).
I've been pondering the efficacy of adding some strategically placed ground straps. Anyone found that doing such is worth the money and effort?

I'm not a fan of that type of cable because it doesn't support as many amps as regular cable at similar prices.
These straps are not meant to carry a load, but for interference grounding issues. They are used to reduce or remove alternator whine from radios and things like that, but not really meant to carry a load. You see them used a lot between body and frames.

Do you disable monitoring in the truck settings? Has that helped with battery life?
This is not the first mention of cables, maybe it was another one of your comments. Since this truck has dual alternators, would that have any bearing on this situation? If there's an issue with the cables, it is right from the factory. I'm not saying it's not possible, we know how good factory can be and how badly they can fail.
Did you figure out your issues with the batteries?
