I got some wings and was planning to use the Rib-O-Lator on my Pellet Pro 22" WSM Stacker with the Cajun Bandit rotisserie ring. I'll definitely post pics of it in action!
Probably not the traditional pellet grill you were thinking of, but, yeah, I got it covered!
Here it is with a Stacker that I used for smoking cheese.
Cajun Bandit rotis ring.
And here is a pic from the Pellet Pro site of a customer submitted setup.
