Hey guys, I'll be smoking pot roast this weekend and had a question. The recipe calls for a six pound roast, but I could only find two 3-pound roasts. I was going to stack one atop the other, and smoke for two hours uncovered at around 250F in a disposable aluminum roaster pan. Then cover up the entire pan with foil and cook 5-6 more hours. Anything I need to modify due to the two roasts instead of one? Or any tips you can add? Thanks guys!
