Thanks everyone for the responses. The turkey turned out Fantastic! This was the first time using a Roaster Oven and it is a great gadget. We stuffed the bird at about 12:30, had it in the RO about 20 mins later. It took about 4hrs to cook and was very moist and tasty. The one thing I did learn is to add more that a 1/2 cup water. We ended up putting in a total of about 1-1/2 cups. (I think that the stuffing tends to absorb some of the steam and/or liquids initally and uses up the original 1/2 cup in no time. The stuffing turned out moist and delicious. We basted the turkey every hour or so with butter/browning sauce/paprika combo and it turned out fine.
Thanks again and we'll be back here more often.
