I came across someone selling a nice looking 18.5" WSM for $100. Said he used it 5 times. May go check it out this afternoon. Any specific things I should check on it to be sure its in good working condition? Anyone have experience with how a whole packer fits on the 18.5"? I would prefer the 22" so I could transfer the rack straight to the kettle but thinking I shouldn't pass this deal up.
