Preparing my truck for a 1600 mile drive this summer

[K10Scottsdale78]

I recently landed a job for the summer to work on a ranch in northern colorado and decided that Im gonna drive my truck out there from home in western ny. Ive never driven that far before, and Im a little concerned about if my truck will make it, its not like I want it to die out when im in the middle of iowa or nebraska. I drove it 7 hours straight last summer to move to move into my college dorm and it had no problems whatsoever. My travel plan is to drive about 10-12 hours a day then spend the night somewhere along the way.

Ive already got new spark plugs, wires and a distributor cap ordered to tune it up, and will be getting my carb adjusted before I leave. I was wondering if theres any other preventative maintence I should do before driving that far.
