All this service is good, but make sure you drive the Vx around the block for a while before taking the long trip. I'm always worried that the job was not done well or sloppy. At least I will still be in town if anything goes wrong. No major service just before leaving.

The usual stuff is :
Change Engine Oil
Brake fluid
Transmission Fluid
Power Steering Fluid
Differential fluid
Grease Up

Check:
CV Boots
Wheel Alignment
Brake pads
Engine mountings
Battery
Spark plugs
Spare Tyre
Tools & Jack
Beltings
Radiator Water
Wiper water
Wiper Blades
Horn
Lights
Leaks or loose stuff under the car.

Bring:
Med-kit
Jumper cable
Tyre patching kit
Tow Cable * (Optional)
Emergency Triangle
Lot's of water

The list goes on, but sometimes it's better to over prepare than under.

Hope you have a good and safe drive.
