Use an igloo cooler. They keep things hot too. Pack up the turkey in one of those disposable roasting pan and foil. Put some towels on the bottom of the cooler and put the turkey in. Pack additional towels around the sides and top. This will keep it hot for a couple of hours.
This is how I transport cooked meats to family functions and it work wonderfully well.
"I must say as to what I have seen of Texas it is the garden spot of the world. The best land and the best prospects for health I ever saw, and I do believe it is a fortune to any man to come here."
Davy Crockett, 1836
