DC mode overrides auto select.
IF RV is level..you can turn fridge ON day/night before to cool it down then load it up with pre-cooled items. (Off level operation when parked will cause damage to fridge)
DC Mode is more for maintaining coolness in fridge while in transit. Not real good for all time use due to heavy draw on batteries.
Once again Old-Biscuit nails it.
Remember to always keep the fridge level. You will wreck it using it in a out of level position. While traveling the bouncing of the trailer will keep the fridge OK.
I am just a weekend camper. I start mine Thursday evening, pack it with cold food Friday morning and then head out Friday evening packed and ready to go.
