Okay, I just installed 4x 6v Trojan T125s.

I would never discharge below 50% as it will eventually ruin them and they will no longer hold a charge for very long. Ensure to keep them topped off by ordering the Hydrolink watering system. It is expensive but any other like the Flow-Rite will void your Trojan warranty.
As for the amp hours, I have the Whirlpool residential refrigerator (side by side) that utilizes 7.2 amps per hours. For my calculations, I added an additional 2.8 amps, which covers lighting, and parasitic device draw and it makes the math easy.
10 amp hour x 16 hours a day = 160 amp hours per day.
Before I go to bed, I turn my inverter off and the refrigerator stays cold.
I can go about two days without any issues. It takes me about 4 hours of running my generator to charge my batteries back up to do it all over again. When I dry camp again, I will report back on exact amp draw per day. I hope this helps.
