Minimum battery voltage while boon docking

We spend long periods boon docking using our diesel generator and a 2000 watt zantrex inverter charger and a bank of three "deep cycle" so called marine RV batteries. We use power liberally for tv, etc.

I know that battery banks are most happy when discharged only slightly, so I tend to use my genset often to keep the charge level up. I currently have been starting the genset and recharging when battery voltage gets down to 12 volts.

How about a simple thread telling what minimum voltage you try to keep before using your genset to recharge? I have talked with people who say they run down to 11.8 volts.

X2 on Wolfe10's comments above. Also, if you just like plinking around and having fun, you might consider installing an amp-hour meter. There are lots of different versions around. You can get simple ones for about $60 that are pretty darn functional. The PowerWerx meter gets good reports: http://www.powerwerx.com/digital-meters/dc-inline-watt-meter-power-analyzer-powerpoles.html.
