We used a sims til it just died. It was replaced with a cylinder stove. If you don't have to pack it in the cylinder is a great stove. The hot water saddle tank is a nice addition. We use the model for a 12 x 14 and it does fine in our 16 x 20 wall tent. We didn't buy it for the large tent...we ordered it with a 12 x 14 we intended to use as a cook tent. When the Sims died we discovered that the cylinder worked fine in the larger tent. Depending on the number in camp we use either the large tent or the smaller but just one stove. Quality is excellent. We don't heat our sleeping tent but that may be changing as we are getting a little long in the tooth.
