I've been looking at those and wondering if I could make a practical portable cooler with it. I usually drive 5-6 hours to hunt elk, and it can be pretty warm. My truck has a fiberglas cap and I wonder if a guy could build a large insulated box that pretty much filled the back of the truck and install one of these units in it. Would be plenty big, I would think,and you could still store stuff in it when there's no meat to cool.
