If you spend about 10 minutes reading recent posts and do a search for turkey, you'll come up with all the help you need.
For me, simple is best as I like a nice browned whole bird for Thanksgiving. So I brine for 24 hours, sprinkle with salt and dry uncovered in the bottom of the fridge for 24 hours.Then stuff the cavity with fruit and sprigs of fresh herbs, brush with melted butter and then smoke at 325˚-350˚ until the IT of the breast is 165˚ and the thigh is around 175˚. For a 14-15 lb bird that's around 4-4.5 hours in my smoker. I like fruit woods for turkey. I've tried hickory, apple and cherry, and cherry seemed the best.
