You will need to anchor it down with a heavy chain welded to the smoker, probably on one of the legs; loop it through a large eye bolt anchored to your deck. Weld the nut to the eye bolt so that it cannot be spun off. Keep in mind that your door is removable so you might want to have someone modify it so that it cannot be removed OR remove the door and store indoors. Whatever you do, don't void your warranty. Check with Steve.
