Chest freezer for garage

When purchase is completed, I intend to have 10 cu ft chest freezer in the garage of my 3010. I am familar with keepingit FULL for efficiency but how would I keep it powered while away from the rig for a 14 day hunt?? It would be spring through fall in Alaska, sunshine is the solar option, extra batteries banked together in the generator area, and possibly additonal batteries in the basement.

Any thoughts and ideas would be helpful.

I used to belong to a hunt camp that had a gas freezer with NO electricity. As long as there was a supply of gas, it would run - but you'd want the room ventilated.
