It's true....bigger is better. You can smoke 2 briskets in the same time as you can smoke one, or, extra shoulders, a couple of extra chickens, or what have you. That makes it more economical than a smaller smoker that has been run twice to produce the same amount of smoked goodness .
Vacuum bagged and frozen, the leftovers can be reheated, saving hours of time, and nobody ever complains about having to eat leftovers, when it's good barbeque done right the first time.
I like to be able to watch a football game on a Sunday afternoon, and enjoy some ribs, or a pulled pork sandwich, thanks to having done the time consuming part weeks or months ago.
Picture having a platter of smoked chicken, pulled pork, baby backs, sliced brisket, and some burnt ends, with little or no effort due to the fact that each was just some extra made with a day's smoke some time ago. That's what I'm talkin' about =)
