Bob, depending on how much food you will need to keep cool, Big Lots and like stores often have cheap 12VDC-powered coolers that will do just what you want. They are the size of a regular Coleman drink cooler. Now, if you have huge amounts of food, that's another story.
If that is the case, you might explore the fire extinguisher recharging businesses in your area. (WHAT???) Well, they often also make bulk dry ice pellets as a sideline, since capturing CO2 is a part of their biz to recharge extinguishers. So here's the deal...you build a cooler box out of plywood and foamboard, with a drawer at the bottom to shovel in dry ice pellets and shelves to hold your food.
Lemme tell ya, dry ice will solid freeze anything it touches. In the bottom of your new freezer box, it will cool it to the right temp and keep your stuff cool a long time. Experiment around, it might be a really cheap way to get it done, and it lasts a long time. Last I bought some, it was like $20 for two big coolers full. They lasted 3 days and still had some left over. You could back up to the place, load the ice in the drawer, then slide it in the box and be good to go.
