"Everybody" says to not drain 12 volt batteries below 12.0 volts. Operating a small refrigerator drops the apparent voltage to 11.9 volts which recovers to 12.5 volts between cycles. Too low or can ...

I think you need a second battery. How long was the fridge operating before you get to 11.9 volts?
Never actually got below 12.2 volts but I used 11.9 to keep it simple. This was with a little 35 ah agm battery that I was evaluating. My posting was to verify that people use resting voltage and not loaded voltage to determine cutoff point.
Resting voltage is difficult to obtain in an RV as there is always something on.
I think most use the loaded chart but still 12.0 to 12.2 is the general recommended minimum.
