Decisions, decisions.... I have 2 roasters about 4.5 lbs. each. Not sure to use the kettle or the vertical smoker. The height might hinder the beer can chickens on the kettle when I put them side by each. Could lay them down and rotate as they cook to face charcoal. Do the two racks on a vetical smoker cook at the same temp? Could put one on each and let it go....... Any thoughts?
