I thought the same thing last week when I made my turkey. The oven is so small that I can't do anything besides the bird in it. My crockpot had just broken, though, so I used a Nesco Roaster instead. (I'm told that you can use the roaster as a crock pot.)
I just used the regular recipe & turned it on. I don't think you'd need to make any adjustments. I know I didn't for the Nesco.
