Calculating AH usage Based on SOC
I have 2 6 v GC batteries with 230 AHs. If I dry camp for x days and my SOC is at say 50%, can I then assume that I have 115 AH's left? Can I calculate AH's used per day by dividing 115 by x? Or say 7...

Yes, your method would work. It would not be real accurate, unless you can accurately measure SOC. That is a problem, as the meter needs to be accurate, and the batteries need to be at rest for several hours. It would be quite hard to do this while the trailer is being used.
I suppose you could also pop the covers on the batteries and do a hydrometer measurement.
For the reasons stated above, most people use a shunt and battery meter of some type.
