After 6hrs smoking, looking good. Internal temp was at 165deg. This pic is right after I took the temp probe out and getting ready to wrap in foil.
I was having a hard time keeping it under 300deg(I've only had this grill since Fathers day, 2nd time using it). Every hour I added about 8 coals per side( Weber suggestions) and a lump of Hickory for smoke. For the first couple of hours it was running between 275-325deg, then I finally got it down to around 300. After 4hrs the temp probe was up to 145deg. After 6hrs it had reached 165deg and I was ready to wrap it. It never did stall, just stead temp rise all day. Only thing I did was to rotate it a couple of times.Fantastic! Hard to believe how fast you were able to get it done? What temp were you at?
