We will be leaving Rochester on Nov 18, we have left as late as Jan 4 and frequently in very cold weather. We always take one night dry camp on the way to our children's house and have never had a battery problem, yet. I'm probably asking for it as our 2 Trojan 105s are original equipment - 7 years old. We have maintained propane refer, furnace and CPAP machine (running direct on 12 V not through an inverter) through the night. Drive time during the day brings the batteries back to full charge.
If we do any serious cooking, we may run the generator for an hour or so in order to have full charge before lights out. We have replaced many of our most used lights with LEDs to reduce energy demand and we now have solar to top things up if we stay put.
We plan on stocking with food as we go, but clean out the house because we will be away for months. We also get the water system up and running before leaving. This means starting the furnace and keeping the coach warm - 55 - until we are ready to roll. that way we are set to dry camp without having to play tent camper with water jugs - been there done that don;t need to go back.
