Looks tasty. I've been tossing around the idea of a rotisserie. Is that the Weber setup? Any drawbacks?
The fit is not the greatest, there is a small gap that makes it harder to control temps. Easy fix is to put aluminum foil in the gap to seal it. I would look into the Cajun Bandit rotisserie ring. A plus to theirs is it also fits a WSM I believe if you have one or are planning on getting one.
