Yes! That's as it was designed! Set it to "auto", it'll be cooling as you travel, no need to switch again til back in storage, as soon as you plug into shore power it will switch over to electric.
There are however a couple steps to insure your batteries aren't dead during storage.
The "use/store" switch DOES NOT totally disconnect the batteries & they'll be dead in about a week due to parasitic drains such as the CO/LP detector. The best & most sure way to disconnect the batteries is to remove the negative cable from the battery that goes directly to ground or remove the batteries & place them in your garage on a battery tender.
So be sure the switch is in "use" mode, batteries are reconnected & propane tank open before starting the fridge.
