Being new to this forum I only recently learned about these UDS's, and I must say am pretty impressed. I don't have a need for another smoker at present time but you never know. It's good to know that this knowledge and experience is out there.
One thing leaves me wondering though. Why do you all not use a heat deflector to create an indirect setup? You could use a large pizza stone, water pan, or terra cotta plant base on a lower level then cook on a higher level. I'm sure there is a valid reason, I just can't figure it out.
