Technology for DC fridge compressors has changed. I got rid of my 3way fridge and bought this Nova Kool 3.5 cubic foot 2way fridge for my Alaskan Camper. The DC compressor is amazing.I just got back from a 3.5 month trip driving around in Central America - think hot and humid - and the fridge never had a problem keeping up and making ice! I have one 160 watt solar on the roof, and a portable 80 watt that I used maybe 10 days. I'd spend anywhere from 1 to 6 days in one spot. While I was driving I also used a Dometic in the back seat of the truck for cold water, beer, and a place to store cold groceries on the road.

Anyway, the DC compressors have come a LONG way in the last few years. Pricey though.
