hello everone in building a back yard smoker its a traditional offest smoker im using 20 in pipe 3/8 thick the main cook chamber is 56 in long im leaning towards one door about 3 ft long or two doors about 2ft long .I know the single door is going to be heavy and might require a counterweight but I like having a open access with out a divider for cooking .I have considered heat loss with the single door but is it a deal breaker? thanks for any advice.
