“Almost all over-the-road truckers have a 12-volt thermoelectric cooler that keeps things roughly 30 degrees colder than the ambient outside temperature. That’s just cold enough to keep my sodas cold and any food fresh for about 4 days. They are an absolute must, so much so, that when my last one stopped working, I stopped at the next truck stop and bought a new one. When I leave out on tour, my wife will set me up with about a 3-day supply of fresh food packed in separate storage containers. Every Truckstop has microwaves available to drivers to use free of charge. Once my 3-day supply runs out, I start looking for a nearby Wally World (Walmart) where I can re-up my supplies.”
