This one was posted in another thread by Norcoredneck. It looks to me like a good design. I think as long as you could get the doors to seal good, it should cook real simular to a UDS, if you use a UDS style charcoal basket. I have two barrells that are waiting patiently for me to get to them!! I love the way that the UDS is very fuel efficient, but I hate doing the "rack shuffel" and I like the ease of entry into my offset, but it is a fuel hog. I think this one would be a good compromise between the two styles of smokers.
