Trying to get some information on the Bubba Grills 250r with the rib smoker. My understanding is that they are great smokers. My question is approx. how many butts can you smoke at one time in the tank part and how many slabs of ribs can be cooked in the rib cooker. Also would love some feedback on the rib smoker and if anyone has smoked ribs in one of these smokers. Thanks in advance.
