I have an Old Country offset that is 1/4" thick, witha 20" diameter by 48" long cooking chamber and a 20 X 24 firebox. Using the charcoal basket and the minion method starting with 2 pieces of oak, pecan or mesquite and dumping a full chimney of lit KBB on top, I can get about 2 - 3 hours at 250 followed by 2 - 3 logs at roughly one hour intervals. If I get distracted and the fire gets low, I throw some RO lump on top and open the intake until things get back to a solid 250. A brisket/butt/rib cook usually consumes a bag of charcoal and a $10 bag of wood from Academy. It's more of a pain than the WSMs, but it's a lot more fun, IMHO.
