My Seneca's coach batteries originally were only "monitored" by the same device that told me my tank levels. Very imprecise. So I installed a real voltmeter so I could have a better idea where they were. Newer unit must have something different if you are able to read actual voltage.
If unplugged boondocking I will use the generator when the coach batteries drop to around 12.2 to 12.3 volts to prevent over-discharge. That reading is taken with minimal to no load drawing them down. I shut off my inverter and make sure the furnace isn't actually running when I take the reading.
