Somebody else pointed these out in another thread.
ElectroWarmth® Bedwarmers - 12 VOLT ELECTROWARMTH® BUNK WARMERS
Their energy use is well within line for what they do, but a big second battery is a must. They are a 12VDC heating pad you put under you. A single bed one at 100% duty cycle wouldn't drain a 100AHour battery's useful capacity over night. They say 50% duty cycle is much more typical. A group 31 deep cycle battery would do fine. In fact it should do one of them and a compressor refrigerator too.
