My tip. Cook, cook, cook. I love my 18.5 WSM. Now I do have a Backwoods Gater on order but my WSM has done me well.
Enjoy it they are a great cooker.
Tips: I got the guru eyelets and love them for getting probes into it.
I've gotten 16 hours on a load of fuel with my stoker on a 40 deg. night. Funny thing was my stoker fan didn't turn on at all overnight, only towards the end of the cook.
