[tentcamper]

We have gone during the summer for 9 days with out recharging the battery. But we are only using the 12v for: lights, water pump, and toilet flush pump. During the winter two nights running the furnace is all we go.

We have a large G-31 12v battery and led lights. We also disconnected the propane detector when dry camping. Outside I use a propane lantern at night.

Just in case, I also bring a good quality set of auto jumper cables. It is easy to jump 2720 with the battery box on the tongue.
