Road trip, your opinion please

[lil hoodlum]

Hello everyone! I am wanting to take a road trip this Thanksgiving to see my parents and family. It is approximately 300 miles each way.

What precautions would you consider for a safe trip?

A little background info. This truck is my daily driver and I believe to mechanically sound. 350 SB, 3 speed manual, no power steering, no power brakes. I do not have any issues, everything works as it should. I don't give a second thought to making a 100 mile round trip in it. This trip,however, would be longer than I am used to making in my truck.

I am planning on replacing both of my front tires as they have some slight dry rot on the sidewalls. I also do not have a spare tire so I would like to get one for emergency use. I also have some new spare parts that I have stockpiled like, water pump, hoses, starter, and alternator. I keep my tools under the seat.

I am thinking about just changing all fluids/ filters and lubing/ greasing the chasis and suspension.

What else should I consider?

Thanks for any input.
