Thinking outside of the box here is an example of the one we use as our Extra refer. It is portable (with two people when loaded). It works on 110 or 12 volts and cools incredibly fast. It holds a ton of stuff and you can set the temperature right down to freezing if you want. No freezer section but you could put frozen stuff in and keep it for many days as it thaws. They have automatic shut off when on 12 volts so they won't kill an engine battery if using in a lighter socket.
