Turkey and chicken is harder to cook and reheat than brisket and pork. Not the end of the world if poultry is required.
If you plan to do pulled pork, pull after it is reheated.
In the past, I have cooked normally, let the meats cool a bit, maybe down to 165-170, then wrap well in plastic wrap, with an outer wrap with aluminum foil. Then reheat in 200 degree oven in the plastic and aluminum foil. If the plastic is a concern, consider unwrapping when internal meat temp is around 100. You may want to rewrap in aluminum foil. Toward the end of reheat, unwrap and let the outer surface dry a bit. If I were serving brisket and ribs, I would start reheating at least 2 hours before serving time, possibly longer if you don't have much help to do other stuff.
Give considerable thought and planning if you must reheat away from your pit or home. Oven space may not be as freely available. If possible and logistically sound, reheat on equipment with which you are familiar and transport hot food.
You also might post this question in the catering thread, especially if you are getting paid to cook. It's been a few years since I have done this and good luck.
