@duff645 Since they aren't making the Pellet Pro/Cajun Bandit Stacker any longer, I'm hanging onto it, but I would suggest getting a donor kettle and cutting out an opening in the bowl for the hopper to mount to.
I mounted this to a Genesis frame, the hopper sits on the lower frame and is secured on both sides with fasteners, the bowl is secured to a strap attached to the frame. Very secure.
I've added a steel disc heat deflector the same distance as the grates under where the waterpan would have been and have 2 full grates. I put a foiled tray for a drip pan over the deflector.
I like this setup better than the Stacker conversion.
