I think I have gathered most of the info I need on here to do my first turkey in the OBS for Christmas Eve. The question I still have is I assume most people put it in breast side up, but do you rotate the rack? I haven't heard anybody say either way. I know it wouldn't hurt, but it probably won't be the easiest thing to do with a 16lbs bird on there. Other than that I will be brining and rubbing that thing down almost exactly like I do with chicken and smoking for 3 hours of hickory at 225-250F and then to an IT of 165-175F. Any other pointers or anything you think I might be missing would be appreciated.
if you have a straight un modified smoker i would rotate the rack every two hours or so, if you have a fan in the smoker you should be fine and not have to.
Good luck with your turkey
I also plan to brine for 24 hours and then rinse the bird off real well and then let air dry in the fridge overnight and then put a little oil and seasoning on it.
No matter what I smoke, I always rotate the racks.
Top to bottom and front to back every hour or so.

I use two racks to support the bird and place breast up. Works for me.
I do mine breast side up and move it around the grate a bit.
