ok so i was talking to my girlfriends dad about his smoker and i was telling him about my temp probs with my SnP...i was telling him how i was going to make a charcoal basket for the firebox and he said that he had the same problem with his smoker and he told me that he flipped his over because it was warped pretty bad...so i tried mine when i got home earlier and VIOLA...i know have like an extra 2 1/2 inches for air flow under the coal grate...you are a genius..
