Got it... used it.... it's great. I'll be doing many "roti-smoked" birds in the future. I used a handful of briquets and some RO, along with hickory and mesquite chips, and it was delicious.
I have one thermometer left over from my CGSP mods. I'm gonna install it on the roti-ring. It'll be nice to adjust the intakes without having to open the unit to determine how it's going.
