Ok, I saw a combined voltage of 14.3V

14.3v is your alternator output. Turn the engine off and go the same page again. You will now see you battery voltage minus the voltage drop due to circuits being used. You can open your hood, shut off the engine and go get a cup of coffee. Bring your key with you and leave it next to the coffee maker. This will keep the truck from waking up with passive entry or you pushing the unlock button waking it up. By the time you have finished your coffee, most systems have shut down and you can put your meter leads on the main battery. This will give you a good idea where your batteries in parallel are ( voltage). Feel free to swap out coffee with another beverage of choice.

The coffee bit is good - but don't use a pot you already have made. Make a fresh pot.
