Stir, for us, microwave, res fridge, 1 A/C, etc are on Line 2. When we boondock, we have pretty much a constant 20 amp draw from the batteries. This is mainly the fridge. The fridge is frost free, so a heater likely turns on from time to time. (I haven't figured out how to turn it off.) I could assume 2 amps shore on Line 2 for the fridge when I want to power share but you know what happens when you assume.
BTW, 1 A/C is on Line 2, the other 2 are on Line 1.
Also, we are fulltimers and split our time between boondocking, friends/relatives and RV Parks.
