I done tons of turkey in my Bradley smoker.
I have used many different rubs to good luck.
I heat the smoker to 225 deg, put the bird in and smoke for 4 hrs, combinations apple for three hours and mesquite the last hour. Continue to 160 Deg. internal temp. then remove from smoker, wrap in moist towel and place in an old cooler for about an hour. The temp will continue to climb for about 40 minutes. Take out cut and serve.
If you like a crispy skin, just smoke it then finish in the oven at a higher temp of 350 Deg.
The same works great for chicken as well, just watch your internal temp.
