Our fuel MPG drops from about 10 to around 8 when we run the ginny for a couple of hours per tank. So that sounds ball park.
Note here that for most manufactures of batteries anything below about 12.2 volts is effectively dead. While you can do this it will reduce battery life. In an ideal world don't take your batteries below 50% SOC or around 12.4 volts.
Check your battery manufactures web site for specific details.

For boondocking with a residential refrig expect to run the ginny about 6 hours. Between 2 and 4 for a refrig on LP. This is if you are using an inverter/charger in the 60 to 100 amp range for the residential or about 30 to 40 amps from a smart charger, which we use, for the refer on LP.

It takes us 300 watts of solar to break even with the refrig on LP, about 3 hours of 2 LED lights and cycling the water pump about half a dozen times to flush the toilet. Solar requirements go up in winter and under cloudy conditions or shade.
We boon dock 6 to 8 months a year.
