They don't give a cubic footage but instead call it a "18 lb capacity" as opposed to #2's "30 lb capacity". It'll definitely be smaller than my gas smoker but if its too small I'll snag a #2 and sell this one. A guy on their forum mentioned a 17 lb shoulder fit and somebody else a 15 lb turkey so that'd work for me. Sounds like it cold smokes well using AMZN tray or tubes. Plus there was a 10% Cyber Monday discount and a free cover. Normally I find out about the sale the day after its over.Welcome aboard. How’s the capacity in the #1 vs. the #2
