Searched but couldn't find info I was looking for. Just started smoking a couple of weeks ago. Will be starting my first butt in a couple of hours. I have a master forge vertical smoker. I have 2 6lbs butts in the frig after rubbing for 24 hrs. My question is do I put both butts on the same grill rack or do I put one on each grill rack? I only have a 1 probe thremo, so I was thinking the same grill rack. Thxs in advance.
