So I just got my 18.5" WSM today. I'm looking at an all-day cook Saturday with either a brisket or a pork butt on the bottom grate and various other shorter-cook items (whole chicken, fatty, wings, etc) on the top grate. The thing I'm curious about is just how long can a fully loaded 18.5" WSM go (minion method) before needing to be refueled? I have a Brinkmann pan being delivered tomorrow to give me additional room, so I was just curious as to what you folks know of as "max" cooking times (assume around 230*) for the 18.5" model. Thanks!
