I recently pulled my 18” WSM out of the shed. I purchased it a number of years ago for competition, but been unused now for a while. I‘m going to load it in the RV for future trips. Just reading this forum, I had never thought of using the hanging technique, I see there are a few product offerings for this. I definitely see that it’s a great way to cook multiple racks of ribs, but curious if there is some advantage if just doing one rack, or tri tip, etc over just using the cooking grates. Never used a drum cooker so not familiar with advantage?
