Furnace and battery
We have a 5 year old 30' Rockwood trailer that we often use dry camping at a local county park that can get cold at night. We have two 6 volt batteries and a solar charger. Before we leave home I ha...

We had a similar experience in the second year of our class C - we were just using the furnace in the morning and one morning it wouldn’t turn on. I had been believing the idiot lights on the little panel which showed full charge after driving. Voltage was over 12.6, indicating 100% charge on the chart in the fifth post here. That chart needs a footnote: accurate only hours after all charging (including engine charging) has ceased. Before that the voltage is the charging voltage rather than the internal battery voltage. With solar charging you will have to measure the voltage before sunup to get a meaningful reading.
After killing my first pair of batteries, I installed a battery monitor that counts the amp hours of energy flowing in and out of the batteries so it can accurately display the % of full charge all the time.
One thing you can do with a voltmeter is check on the charging. Batteries need to get over 14 volts for effective charging.
