I always use a nesco roaster. I can give you a real nice hint.. Iclang had the issue of a frozen turkey. Those are the best way to cook a turkey. You have less of a chance of contaimination, and your turkey will be the most juicy bird you have ever had. Just run some warm water in the cavities to remove the giblets and neck.. season and place in your roaster/oven and for a 20 pound turkey it takes about 7 hours to cook. So the cook time is longer, but so worth it. I never ate turkey on Thanksgiving day because it always seemed to dry to me, and more so the white meat. Now I can..cuz now you can actually see the juice drip from the white meat.
