I have a new camp chef pellet smoker, model # PG24. How many pork butts can i fit on it, i need to fix enough pulled pork to feed aprox 60-75 people. I calculate six eight pounders should do. I hope i can fix them all at the same time. Also i have never smoked so much meat on any of my old riggs, any ideas on how long the cook time will be? Thanks for any and all reply's.
