Another thing that will help the draw on the battery is to ensure any receptacle that is connected to your inverter if unplugged as most devices still have a parasitic draw. Let me know how it works for you. I will be doing some boondocking and testing out the batteries in the next couple of weeks and will be sure to let everyone know how it goes.
*I forgot to mention that we keep our ice maker off. That saves quit a bit of draw.

These are some good pointers, our friends run theirs over night with the ice maker, a couple of hours of T.V. and LED lights for about 3 hours after dark. I measured the amp draw when the refrig cycled and it was 17 amps for about 10 or 15 minutes. When ginny hours commenced at the CG they would need to run it for 4 to 6 hours with inverter/charger outputing 60 amps into a 432 Ah bank of which~ 216 Ah had been used from the time the ginny was turned off the previous day. That may give some idea of what a solar system has to make up during the day. If your shooting for a 10% rate of charge,ROC, that's 43 amps until absorb is reached. Typical ROC for deep cycle batteries is 10 to 13%.
