Really excellent there's a site like this so focused on one great thing.
I'm hoping for some guidance in finding plans for a 24" x 48" (or so) offset horizontal. Raised firebox, lowered chimney like Franklin and Jambo
Any ideas would be a big deal for me.
I joined because there's a lot of discussion about smokers, particularly the top-down vented pits like Jambo and what Franklin does. I'm probably going to have someone build the pit, but came here to learn more.
