I know the answer is, when it's done it's done. LOL But I'm looking to guestimate how long my smoke will take. What I have sitting in my fridge is 3X 9lb butts and a 13 lb brisket. I will be cooking on a chargriller outlaw at 225-250. I am thinking it's going to take roughly 14 hrs, is this a good estimate of time or should I prepare for something longer? I need to be ready at 500PM Sunday to eat. Also, how long will the temps hold after pulling and putting in a cooler?
