Getting my parts together for a fancy new UDS. Tired of the low capacity and babysitting my offset. I think I have everything figured out, but wondering about the cooking grate distance from the top of the drum. Seems that most guys do 6" or so. My concern with that is if I wanted to do a chicken standing up (like a drunken chicken) there wouldn't be enough head room. I don't want to mess with trying to get a dome lid. So I'm wondering if there is a specific reason most set there grate about 6" below the lid? Pretty excited to build a UDS!!!!
