I start mine plugged into shore power on propane a couple of days before we load up. Then battery/propane on the road and shore power/propane at the campground. I've never seen one that runs on 12vdc alone.
That is what we do with ours too.
Our first trailer(Casita) had a smaller (4 cu. ft.) fridge that was 3 way and used 12V for the heater when the 12V mode was selected. The 12V heater was lower wattage than the 120V heater so even if fed by 12V it did not provide as much heat to the system. I thought that was the way to go when traveling but found that it pulled too much current to operate properly while traveling so we switched to propane. Most absorption RV fridges are too big now to even attempt 12V only operation.
