Maybe they changed the WSM design but the Weber rotisserie I had did not fit securely on top of a WSM, the lip and lid on the kettle and the WSM are different. IMO you don't get near the benefit using a rotisserie at lower temps, or even at the further distance from the heat source on a WSM. I just use my rotisserie on the kettle at grilling temps and if I want a hit of smoke I'll drop some wood chips or a chunk onto the coals.
