Residential Fridge versus three-way in a Class B or C

Off-grid, have a propane fridge.

We tried a 120v only 3.2 cu ft fridge in the TC we had. We had four batteries at about 440AH and 300w of solar. If the sun shone every day we just got by, but any cloudy days no can do. The fridge on inverter is not the only 12v item in the RV either.

The res fridge eats AH, so they are great if you usually have shore power, but are basically unsat off grid for any time more than a few days before you get shore power again.
