Hmmm. Since you've replaced the timing belt, water pump, and most of the oil seals recently not a lot in that department.
Make sure the spare tire is inflated and the jack & tire iron are in place. Check all your tires. Make sure all fluids are topped up, especially the bug washer. Check credit limit on credit card, make sure sufficient for major repair

. Maybe get a AAA membership or something else that will pay for a tow...getting towed when you're between Bumfuk and Snakenavel can get expensive. If you're heading south, test your A/C
before you hit the road. Make sure you have enough tunes to keep yourself sane on the trip.
