If it were me...I would prepare it to serve and then cool it down as fast as possible and freeze until you are ready to travel. Keep it in a cooler on ice and let it thaw a day or two on ice or refrigeration. Reheat in the oven by adding some apple juice for moisture and a bit of rub and some sauce if desired, cover with foil.
