Smoker

Question

I've kashered the smoker I fouund in the trash as you suggested. My question is now the following: I'm planning a backyard pary for a few friends - most are non Jewish and I'd like to smoke some pork loins for them and some kosher meat for the rest of us. Can I spread the pork on half the smoker and the beef on the other half, or should I first prepare the pork, clean the smoker, then do the beef, or vice versa. I'd prepare beef for everyone, but most prefer the pork. Please let me know the process.
