Okay, I measured 12.74V at the pair of 6V batteries using a good quality volt meter. The volt meter I installed on the kitchen stove hood read 12.70V. So it is reading a tad bit less which is to my benefit, indicating the batteries are 0.04V less than they actually are.
I also bought a 12V plug-in volt meter that reads to only one decimal place. That meter read 12.8V. The 12V socket happens to be located in another area of the rig which may have changed the dynamics a little differently.
On our next trip, I will see how it all goes with loads and such.
I think all is well and I am good to go, ready for the next adventure, and a little better prepared in this regard.
I am really pleased with the change-over from two 12V lead acid batteries to two 6V sealed AGM batteries. And now I can monitor their drain better, charging them before any damage is done.
