Hi GordonThree,
The duty cycle on the Dometic in my RV is 2:3 with the door never opened. The Norcold may be similar. That brings daily usage by just the fridge to around 40 amp-hours per day. Other folks have reported 36 amp-hours per day.
The real answer depends on the particular fridge make and model. One fellow on facebook claims 12 amp-hours per day.
I suppose 12 is possible, if the door is never opened, door seal heater off, and low ambient temperature... lots of variables.
I'll soon have individual load monitoring on my RV, for no reason in particular other than I like to have the data.
