I had planned on updating this thread throughout my cook, but it didn't work out well...
So I started out with brining the 14 lb bird last night. My brine consisted of a gallon of apple juice, 2 cups of kosher salt, 2 cups of dark brown sugar, 1 cup of regular sugar, about 5 oz of ginger thinly sliced, and 4 cloves of garlic roughly chopped. I brined the bird for about 12 hours, took it out of the brine, rinsed it off, patted it dry with some paper towels, and then let it rest in the fridge for about 2 hours.
I lit up the cooker using the standard method and used 2 full chimneys of charcoal. I used apple wood chips, as I didn't have any chunks on hand. I put the bird on at about 9:45 am and the smoker settled at about 350, measured at the lid. The cooker held this temperature for about an hour and a half, at which point the temperature abruptly dropped to around 310-320 measured at the lid. I opened up the door and noticed that some of the 2nd chimney full of charcoal never really got going. I gently stirred up these coals and w/in about 5 minutes the cooker was back up to 350 and didn't budge for the rest of the cook.
At about noon my thermometer was consistently measuring 160 throughout both of the breasts, and the thigh was reading about 180-185. I took the bird off after only 2 hours and 15 minutes. I was pretty surprised at how quickly the bird was done. I left the bird to rest lightly covered by aluminum foil while my roommates and I worked on getting the gravy and sides ready.
A little aside on the gravy here - the drippings that came off the bird were unbelievably flavorful. The gravy I made was some of the best I've ever tasted.
I carved up the bird and my friends and I began to dig in. The breast meat was amazingly juicy. The leg and thigh meat showed good smoke penetration, and had a great smoky flavor. I think one thing I learned from this cook was that I could have done with less smoke wood. Though my friends and I enjoyed the flavor of the dark meat, I think I would have preferred just a bit less smokiness.
Overall, the first turkey cook was a great success. Here's a link to some pictures I took.
