I plan on using a 7 cu.ft. chest freezer as a fridge (a fridger) with an external digital thermostat. Its power consumption will be much less than even the most efficient upright fridge, and all the cold air won't fall out every time you open the door! Australians off the grid have embraced the concept of fridgers*, and my bus has plenty of solar power (just like many Australian bus conversions), so it should work well. At about $250 in total it's also MUCH cheaper than fancy 12VDC high-efficiency fridges. I'll run it from its own dedicated inverter, the smallest one that will start it, to avoid needing the big Magnum inverter on standby all the time.
Another incidental benefit of having a chest fridger is that I can have a single countertop (hinged to its lid) above it and the front-loading washer/dryer next to it, greatly extending the usable workspace in the kitchen area. Also, not having a tall upright fridge will make the kitchen appear less cluttered and more spacious.
With about 2kW of solar I really shouldn't be too concerned about power consumption, but why use more power than necessary? I want to be OK even if the sun doesn't shine for three days, so everything I can do to save power is worthwhile.
