During the winter, I carry a axillary electric heater. It has an trolling/RV battery, in a marine battery box. With an electric heater (12V, 30A) bought from a truck stop. A relay that is fed by the cigarette socket in the volt with a switch to turn it on and off. and a voltmeter for the battery. This enables me to leave the heater off in cool weather and in cold weather gives a little boost. it Saves about one kilowatt hour.
