Pretty exciting! The wait will be worth it! The Maverick has a clip that allows you to clip it to the shelves, so no need for foil or potatoes. Gregg's absolutely right about not monitoring box temp while seasoning. Temps are crazy, and not an indicator of how it will perform full. Also, don't bother foiling anything for seasoning - save it for the meat.
Good luck, and let us know how we can help!
