I know a lot of these probably get posted. I have had an electric smoker for last few years but ended up melting it this last winter after putting a blanket and plastic bag over it to hold heat. I am looking for an efficient design for a UDS. Please give me your .02 and if its out of the norm of everyone else please provide me reasoning as to why you think its a better option. Valve location and design? 30 vs 55 gallon drum? Domed lid vs flat drum lid that comes with it? Basket material, design and size? Dimensions for mounting the racks? I would like to get two racks in it. Any links and pictures would be very much appreciated. Thanks in advance, I am excited to get this build planned and built over next few weeks.
