Like keelhauler, I have used that little Coleman Grill Stove for about ten years now. I bought it for the small space required when we had a Class B Roadtrek. I also carry a Coleman single burner and with the two of them we can cook just about anything our little hearts desire. Disposable LP gas makes more sense to me than being tethered by an umbilical gas hose to a big bottle or the rv LP source. If we are just making coffee or warming some soup or something, I only pull out the single burner. Full meals bring out both.
Since we boondock mostly and for many days at a time, we have to plan all the cooking and supplies rather carefully.
