12V-only is better than 120V-propane or 120V-only if you camp mostly offgrid AND have a substantial solar system AND your climate and terrain favor solar energy harvesting. Or if you have a big Li battery bank sufficient for a typical duration of your trip. Or if you're prepared to run a generator couple hours every day.
6 cu.ft 12V fridge with say, 2 cu.ft freezer, will draw 50-70 AH a day (compare this to 8-15 AH of thermostat draw in propane fridge). You don't want this extra burden unless the above conditions are met. For the same volume they tend to cost more than 120V-propane or 120V-only, and for people camping mostly on hookups they don't make sense compared to 120V-only or 120V-propane.
