Very true, but only part of the story. If you are using the tank heaters, there is a pretty good chance you are also using the furnace quite a bit, especially in a poorly insulated ultralite. In my case I have 4 tanks (2grey, 1 black and 1 fresh), so 21.6 amps plus the furnace = getting up in the middle of the night and starting the generator!
How do I know this? Well....................
