I've been toying with adding a vertical pellet to my Gridiron. I loved the vertical case design of my old Smokin-It Model 3 for jerky, wings, etc. ... even ribs. Out of curiosity, did you get the 3 Series or 5 series?
Also, I assume no issues with the higher side temps to get the skin on the wings crispy?
I am not sure what number series it is. It is the Pro Series sold exclusively at Lowes.
At 400 degrees the skin comes out perfect. Just use the top two grates and do not add any water to the pan
