Thanks for the comments guys.
If you haven't done this try it. It's very easy, only takes about 45 min to cook (maybe longer) and you can always just add 3 to something you are hanging if you have a hinged grate. I'd make at least 3 though.
Oh speaking if that, I usually make at least 3. Eat one right away and let the others cool down, then vac-seal them and put them in the freezer. When I'm ready to eat, I thaw one then put it in almost boiling water for about 15 min. It'll heat through and taste as good as first cooked but not dry out. I use that technique with a lot of smoked foods. Pulled pork is great like that!
