If you're going to Florida make sure your Air Conditioning works going full blast. Do heavy waxing on the front bumper and hood, those bugs will be coming at you mighty fast, that also means get the heavy duty winshield-washer fluid that get's bugs off. At 12K miles you shouldn't have any major issues, and it being a Ford there is usually a dealer close by, you might want to search for an SVT specific dealer along your route just in case the standard Ford dealer can't do anything for you.
Don't forget your credit card, sun screen, and most of all have fun.
