I built a stick burning reverse flow smoker 3 or so years ago now. I did a build thread on it here. Its been a great unit and I've had zero complaints from the friends and family as to its effectiveness. I have only two issues with it and they are both related. Its a wood eater so it requires fairly constant attention. Its not so bad when the smoke can be done during the day but longer smokes require me to be up all night tending fire so longer smokes like brisket doesn't happen near as much as id like. Thinking about a gravity feed smoker like the Stumps, Southern Bred, Rebel, Assassin etc... Any preference on one over the other? They all pretty much work the same way. I'm liking the small Southern Bred unit that's got the built in air control. Looks like its big enough to do most all of my needs. What's the skinny, who's good to deal with, comes thru with their promises and delivers product on time?
