Back to Moose's original thought on the Air Bake pan system. Those are pretty neat in that you put everything in, heat up the closed, double walled pan/pot until the top thermometer registers the right color (red, green, yellow) for the thing you're cooking, then take the pan OFF the stovetop and place it in it's insulated travel case, and then go whereever you want while the food is continuing to cook for hours. This would help when you want to leave the anchorage, and don't want to wait around until the food is baked, cooked, whatever.
They are also kind of like an "on-the-go" crock pot. You just put all the stuff in, heat it up to red quickly, take it off the stove and put into the insulated carry case. You can cook bisquits and cakes in them also. That would eliminate the need for the 110 V hook-ups.
They would be good for chili on hunting trips, esp. duck hunting. People can open the pot, eat, and close it back up off and on for hours without outside heat. With my three active boys, it was hard to get everyone to eat at the same time, but the Air Bake keeps the food hot for hours, even on hunting/fishing trips.
