I never travel with a whole cooked turkey. I smoke the day before Thanksgiving, slice and arrange in a disposable foil pan, cover with foil, and refrigerate. I take it cold to my destination, remove the foil and drizzle with some canned chicken broth for some added moisture that steams the meat, refoil and heat in a 300*F oven until the meat hits 140-150*F.
Here's an example from a few years ago on the right with some tiny apples as decoration.
