This is not correct. On a Dometic fridge, the "Auto" setting prioritizes between AC and LPG only. The Auto setting cannot select DC operation.
I have upgraded the charge wiring between my truck and camper and always run on DC while underway. My Dometic fridge maintains the same temperature regardless of the power source.

FWIW, the DC heating element in my fridge draws 18.9 A @ 14.7V.
When I am driving, my LPG bottles are OFF.
