Okay fair enough. I still don't think the powder coat truly insulates the entire cooker in the traditional sense. Could it help? Sure but I'll put more blue chips on it being mostly because of the smaller size of the drum. There is less air that the fire has to heat and can heat the air that is there faster and more evenly. Just my opinion.
