My biggest concern with Propane is availability. I know is some places they sell propane at gas stations. They don't do that where I live. You'd have to go to a bulk retailer to get propane. For me it would be a pain since none of the bulk retailers are along my route. And 9 times out of 10 it would probably require multiple trips to get the tanks filled. I'd hear something like "Tommy's not here right now, you'll have to leave your tanks and pick them up later".
