Just bought the Alaknak 12x12 outfitter 2 tent. it has a stove jack. I see there are different sized stoves you can buy. The one I have my eye on says its good to heat a 16'x24' space, the one below that one says its good for a 14'x16' space. Id rather have the slightly larger stove I think but im just not sure if its actually needed. This isnt for full on winter camping and hunting, just Alaska fall time hunting season Sept-Oct.
