I have been trying to watch and see and I do think my basket burns a bit better on the side of the exhaust but I have been chalking it up to the dripping from the food causing this as I keep the exhause away from anything in the smoker to avoid any 'liwuid smoke' dripping on them.
I'm out playing with my drum now so I'll take anothr look.
Slappin that bass like some delerious funky preist!!!
