We're trying to reduce the amount of frozen food in our freezers (which resulted from me buying my first Egg a few years ago and then going crazy buying meat everytime I saw a good deal :P ) So I thawed out a 17 1/4 lb turkey that I actually had gotten for free with some "bonus points" at Giant, seasoned it and cooked it in my MBGE I keep up at my hunting camp. It was a tight fit, but it turned out great.
Part way through the cook-Egg at 325*
It took over 15 minutes per pound because even though I took the bird out of the freezer 7 days earlier, it was still slightly frozen on the inside when I went to cook it.
When I stuck the Polder in it, it was 32* deep in the breast, but I was committed to the cook, so I went with it.
Thanks for looking.
