I just got a masterbuilt 40 and about to do my first smoke. I ordered a #3 package from the a maze n pellet site and thought I was getting a 6x8 but turns out it is a 5x8. Is it too small? can I do with this I really want to get started. I wanna do brisket and pork belly, wings, everything really. Would like to let it sit over night without having to get up and change things around. Lemme know if I should return it. I'd rather not though. I got a cookout plan for monday. What should I do? Thanks everyone!
