I am in the process of upgrading my old Little Chief smoker, and am leaning towards either a MES 30 or 40. I usually only cook for my fiance and I, but I would like to be able to smoke an occasional turkey so I think the 40 would be the logical choice. Would all that extra room be detrimental when I'm cooking something smaller? I'm new to all this, so any input would be greatly appreciated. Thanks!
