Like Mike837 we boondock ALOT! Also piggy backing with Jeff1963.
Two good quality batteries and judicious power discipline can stretch usage time on battery a long way. We camp/hunt periodically for extended periods, sometimes in temps well below freezing.
In fact, myself and two close friends just completed a 7 day hunt in the back country and were exclusively on battery power. (We couldn't get the generator started and we did not plug into the tow vehicle.) Many days, the temps were down below 30 degrees. Yet, for 7 days, the batteries never went below 2/3rd. We would turn on the water heater in the morning (on gas) and let it run till cut itself off and shut the switch off. we would turn it back on while we ate dinner. We would only turn on the water pump when we were actively running water. For heat, we would use a Mr. Buddy heater inside. We religiously used our battery headlamps outside, and once we came in for the night we only lit one light in the trailer. On one of the rainy nights we used a colemen propane lantern inside. This both lit up the inside and provided lots of heat.
I have two 12VDC deep cycle batteries wired in parallel. When they go, I will be replacing them with two high quality high amp hour 6VDC batteries wired in series. I did this on my old 5er, and the 6s do last longer.
We are just a humble drinking couple with a hunting and camping problem.
