Whilst this is an excellent method in many ways, I thnik it would be easier to cook the stew(s) at home, then dehydrate the finished product, then all one needs do at camp is rehydrate and heat. All the suggestions I have seen recommend cutting meat and all other foods to the smallest possible size, or they take for ever to rehydrate, so ground meat in stews is preferred to chunks.
One thing to consider, if you cover your dried meat withj water and leave for some hours to rehydrate before cooking, it will be a wet food in the danger zone of 40 to 140 deg f for a considerable time, which encourages bacterial growth. IMO, that's why fast rehydration is required for me. So I pour boiling water over dehydrated cooked foods for both safety and time condsiderations.
