I have been lurking here for a couple months. I have a 2 stage plan to first either build a UDS or an offset smoker using 55 gallon drums I have available to me, then later build a reverse flow with something more substantial like an oil or air tank. I will be starting off by doing some research into what the merits of a UDS are. I also have a small amount of experience and a large amount of research with roasting whole hog. I did a half Berkshire hog last summer for some friends and had pretty good success. I used a rig made of 40 cinder blocks and a custom cut sheet of expanded metal. We loaded it with mulberrywood coals all day and it was quite delicious and tender right off the bone. I probably have more questions than answers at this point, so please endure me. Thanks!
