With only 80K miles, I don't think I would worry much as long as you do a good inspection of things before you leave--like belts, etc. You should know your oil usage to determine if you need to take oil as well as any other lubricants. If tires are in good shape and spare full of air--good to go in that area. Gas her up and let it rip.
I picked up my 96 (150K miles on it) in Scranton, PA and drove it all the way to New Mexico. No problems whatsoever.
