Would I be safe to drive a 23 year old truck for 7 hours / 450 miles? [closed]

Apologies in advance if this question should be posted on the mechanics Stack Exchange rather than here, but after seeing a similar question or two, I figure this one may not hurt:

I've been driving a '96 Chevy S10 for about five years now, and coming from a family of mechanics and/or vehicle enthusiasts, the truck's been pretty well-maintained in that time frame. I'm on a brand new set of tires (not even two months old), I just refilled the coolant, the oil is fresh, the current heater core has not even had a year of use, etc. It's sitting on about 147k miles.

Against all odds, I somehow managed to get an internship for the summer that's all the way in New Jersey. I live in Virginia. I (with the advice of friends that have travel experience, whereas I have none) have already established that it'd be cheaper to drive there (rather than fly), and I would need a vehicle for getting around once I'm there anyways.

The route seems to be mostly highway/interstate driving for miles on end, which should be pretty smooth on the truck.

So, in summary:

• Well-maintained '96 Chevy S10 with 147k miles
• Virginia -> New Jersey, 7hr, 450mi trip
• Mostly highways/interstates

Would it be safe to make the journey? Or is the paranoia from parents justified? Let me know if more information is needed.

edit: Is there anything outside of vehicle maintenance/check-up and self-preparation that I may be forgetting that'd be a good idea to prepare for?
