Gas or Electric (residential) Refrigerator?
Six months ago we were in a head on accident that destroyed our RV and despite still being shell shocked we're now considering having a new one built to our specs. The last 3 trips in the old Bea...

15 KWH/ month is half a KWh per day, so a 100 watts of solar collector could run it.
I doubt that flat 100W will run that Sunfrost 16 in most scenarios. This fridge alone would require about 180W in summer.

I don't see any prices for these fridges.
Because shops don't want to carry them, there is no demand at these prices :)
It's all about the fridge interior volume and insulation - the smaller the volume and the thicker the walls, the less energy it draws. Sunfrost RF16 has thick walls, rather bulky outside for its 10 cu.ft total volume, and in the end it saves ~15-20 AH a day over a same capacity 120V fridge. I don't know where Sunfrost Co. got th number 75 KWH a month for an "average fridge" (while their RF16 draws 15 KWH). Average 120V fridge of this size - unless made 30 years ago - draws 30 KWH a month, make it 35 KWH with inverter loss. With extra 2" of insulation to make it same bulky as RF16 there will hardly be any energy difference worth talking about (other than 5 times the cost).
