What's a 12 cooler?

Is it better than a Coleman?
Why bother with a cooler in Winter when one can just place cold items under the Bunk (for those that HAVE under the Bunk storage)?
One CAN SAVE a lot of wasted money by NOT EATING THE SLOP offered at any truck stop.
Go to Walleye Wurld and buy a mess of canned goods especially of Veggies and Fruits.
Get a small manually operated or Military Field can opener.
Go to Wendys for the Plastic ware.
Get some Crackers, Bread, other goodies, etc...and make your own meals IN THE TRUCK. Eat a carefully selected meal out of the truck once a day or every other day that isn't some fast food slop house.
Microwave(provided it is not able to drain batteries or blow fuzzes), 12v Crock Pot or similar, Coffee Pot 4-10 cup with 1000 watt Inverter.
Park IN THE BACK or the furthest from buildings at truck stops and other places when/where feasible for the extra walking distance/challenge.
Buy smaller sized clothes and work yourself to fit them.
Incentives help.
