I run a 11 cu ft whirlpool in my toyhauler, I have 200 watts solar and 2 gc-2 batts I have been dry camping for 4 and 5 days at a time with no problems whatsoever, I run the genny for a couple hours at night anyways so it tops the batts so far I have never ran down the batteries past 60%, I'm using a 1200 watt pure sine wave inverter. Also it only takes an hour or so to get cold, it works much better in AZ in the campground than my old absorbtion fridge and I have an icemaker now to boot connected to my reverse osmosis system.
