Check your tire pressure, make sure your serpentine belt is in good shape and not cracked and check your water hoses to make sure they're not buldged which indicates they're rotting on the inside. Also make sure your coolant level is correct and since it's a winter trip I'd put winter formula windshield washer fluid in the reservoir if you haven't done so already. Goodluck and enjoy the trip.
