I get asked a lot about how I keep on my budget, and eat healthy while on the road.

I picked up a cooler that plugs into my cigarette lighter.  This cooler is the one I have.  The cooler says it will cool to at least 40 degrees less than the outside temperature.

I have had the cooler for a few weeks.  I keep a gallon of water, mustard, ketchup, relish and some other beverages.

The only thing that I would point out, which is common sense, but watch out if you plug this device into a full time power outlet.  This thing can not be run on your battery for more than 2 hours, or you will risk your battery being killed.
