I love my WSM and enjoy using it.
However, there is one thing that really pisses me off! Though, more than likely it's an operator issue.
The center ring/section sticks to the lower charcoal bowl to the point where on my last smoke I couldn't take them apart. It was a PIA to start a fire. I haven't done it yet but, I'm assuming that after being used and the smoker still warm it'll come apart easy and a quick wipe-down should take care of my troubles. The dampers stick pretty good also but come loose fairly easily. I will definitely put some wheels on the beast because dragging it in and out of the garage is getting old also.
Do you have any issues and/or solutions?
