Yes you can run The Furrion Arctic RV Refrigerator with Freezer Matte Black - 10 Cu Ft - 12 Volt # FR42SR on a deep cycle battery.

Not knowing your exact battery I can not give you a time frame.

A 12 volt 105 AH battery can supply 1.26 kilo watt hours, under perfect conditions.
Deep cycle batteries are designed to run down to 50% capacity then require a recharge. That said we will take 1,260 watt hours divided by 2 and you get 630 watt hours of usable energy.

The Artic RV Refrigerator uses 1.08 kilo watt hours per day so you would get a few hours out of it if that is all you used the deep cycle battery for.
