I've got two that use the thread on msr canisters, between the wife and I we carry 4 8oz cans and while we've run low haven't had an issue with running out and they seem readily available in my experience. For back up we carry a Vargo hexagon wood stove, it folds up fairly small, weights nothing being made of Ti. Not certain in fire prone areas if it qualifies as a campfire, I'd assume not being enclosed on 5 sides with a pot on top, it can be fully enclosed when done using it.
