I have a weber lid which fits very well. The barrel is 34" tall. I am planning to construct the bottom of charcoal basket 3" off the bottom; place lowest rack 24" above the floor of basket. If I drop 1" from the top of barrel to place top rack, that gives me 6" between racks. This 6" does not seem like much room between racks. Am I just over analyzing this? Am I good to go with this plan?
