The wife caved in and let me get a Big Block. My question is, what is the capacity? I can see that it has "x" amount of cubic inches, but how many pork butts can I comfortably cook if I had to? I know it's extra wide, but how many slabs of spare ribs can I cram in there? Lots of adjustable shelves, but how many briskets can you do at once? Has anybody ever smoked chicken wings? How many of those would it take to fill all the shelf space?
