I am with scott in regards of loading your self with stuff that you really don't need to carry with you.
Screw drivers,plyers,jumper cables and a flash light is what you really need to carry because if happens that the VX breaks down ( God's spare you ) is more likely you may need to have tow it to the nearest mech-shop anyways

1rst aid kit ? .......seriously ?

More important make sure all electrical are working,especially the brake,parking,headlights & hazard

Check that all caps are tight close ( engine.radiator,brake,steering,etc )

Before hitting the H-way check all fluids,especially the engine oil and make sure is fresh oil in there,also the tires should be properly inflated ( for TOD purposes )

Grab 1 or 2 quarts of engine oil and take it along with you.

THIS IS VERY IMPORTANT >>>>Since you don't know yet how much oil the engine may consume i'll suggest you make a 10 minutes stop @ every 100/150 miles to check the level,that can help you figured out @ which amount of miles you need to add more oil again.

I wish you the best ride back home and above all a safe ride.
