The LP/AC/DC fridges are ammonia type absorption units. They are not really what they appear to be. Liquid ammonia is heated causing vapors (gasses) to expand and rise where they absorb heat, causing the gas to condense back to liquid and return to the tank. That works pretty well with LP, but you still need 12v to open the LP solenoid valve and power the control. So it is not just LP. In the AC mode 120 vac is sent to a heating element that heats the tank, also works OK but much less efficient than Freon/compressor style. In DC mode they are terribly inefficient. Resistance heating gobbles power fast and yields little cooling power. Also they constantly produce heat adding to the inefficiency.
12 vdc/ 120 vac units are more efficient, chest type better than door style. Even a small domestic 120 vac fridge run from inverted 12 vdc is better.
Of course all of this is IMHO. I think if you crunch the numbers you will agree.
