I question the 12A number if indeed you have a Jayco popup. Can you tell us the make and model of the furnace to double check that figure?
Maybe you have a big highwall unit with a bigger furnace? My Baja uses the Atwood 7916-II (very typical popup furnace) which is rated at 3.5A. Basically the DC draw is from the fan motor.
Agreed, I use 4A to estimate. A healthy group 24 has ~80 ah (20 hr rate) to ~100 ah (1A rate). I divide 80 by 2 and get 40 ah usable.
40 / 4 = 10 hrs of furnace run time to use. That could be 1 day if it is cold and windy or many days if the furnace doesn't run much.
