First, my thanks to all the great contributions of the Brethren and Sistren in the UDS Thread. My goal was to use best ideas I saw to produce a very simple stainless UDS.
This has a Weber Performer Lid with the built-in thermostat and the stainless draft door from Big Green Egg.
Removable lid seal insert made from old Bar-B-Kettle bottom cut to leave 2" w/ Rutland stove gasket attached to it with high-temp silicon.
(Trial run last night was a 14 lb brisket packer, cooked at 300 degrees until probe tender in 5 1/2 hours. Outdoor temperature was low 20's w/ snow showers. Cooked it Lockhart style with outstanding results -- thank you Funk for all the great info you have shared.)
I am going to add handles, but not much more. I like the simplicity.
