Saw a few threads mentioning Smokin-It smokers and was wondering how they are for low temp smoking like sausage/snack sticks/bacon. I have a MES40 that I upgraded with an Auber PID controller and circulation and it works pretty well but I'd like the option to be able to hang more than 15lb without it feeling cramped. I was looking around and saw some mention of airflow being an issue, does it have issues drying the casings?
