The DO is not the heat source, and not cooking anything. If a foil pan is legal, a DO is legal, as long as they are both USED in adhereance to the heat source rules.
I say, knock yourself out with that DO as long as it is contained in a smoker or grill that adheres to the pellets, charcoal, wood rule.
Now, about those darned pellets and "electrical accesories".....
