The only way we heat food is with a two-burner propane stove. These typically run off the small green bottles that cost $3 a pop, but we were able to purchase an adapter off Amazon.com that hooks into a 15-pound tank most often used for grills. We created a shelf that hooks to the back of the bed and is covered by the tailgate to protect from rain, but it can still get pretty windy back there. As anyone who has used one of these stoves can attest, it is difficult to control the heat so constant stirring or non-stick pans are helpful. We mostly use enamel-ware straight out of the 1950s that withstands the rigors of travel and cleans up quickly and easily. We usually use a lid while heating that traps the warmth and provides more even cooking. This efficient system has allowed us to cook quality meals in the middle of busy parking lots, roadside rest areas, and dirt road pullouts where we sometimes spend the night.
