When I did smoke turkeys I would stuff them with an apple, bread, crushed crackers, celery, onion and some Bells seasoning. Slow cook bird covered in foil at 225F. Depending on the size (I’ve gone as big as 27lbs) is how long it takes to cook. About 3/4 of the way through the cook (approx 140 internal temp) I would then baste it with orange marmalade with lime juice. Touch of ground black pepper. Finish the cook to internal 165F. One last light application of baste and let it sit 25 mins or so. It will fall off the bone just fork picking.
