How long will the RV battery last boondocking?
There is a different answer to this question for every RV. As an example:
In 2011 we spent 2 weeks boondocking in Yellowstone National Park in September. The days were warm enough there was no need for a jacket, but the nights got down into the mid 20's. Cold. We got there with a fully charged battery. The first night, we set the furnace thermostat at 65 degrees. About 3am, the battery was dead. The next morning, we used the generator to charge the battery back up to an estimated 80% SOC or 90% SOC. Every night thereafter, we set the furnace thermostat at 50 degrees, and slept under 2 comforters. First thing in the morning, we set it back up to 69 degrees, and in 15 or 20 minutes, the RV was warm. We got 2 nights out of the batteries doing that.
So, on that one trip, we had 6 hours and 48 hours on the same batteries in the same RV. It depended on our usage.
