sorry i'm just starting to smoke but i have a few questions. 1. i'm having a hard time keeping the temp below 250 on my charcoal grill. this has the smoke box on the side. also i think i am pulling the meat off the grill to early. it does not fall apart like i have seen it done. i pull it off when the internal temp is at 140 degrees. plus with all the work i put in to this i thought it would taste better i must no be using enough rub or the wrong ingredients. please help me what do i need to do.
