If you have not maintained the vehicle I would not take a drive of this length unless I was an adventure freak! I do a 500 mile trip about once a month and every time I go, I check tires Tread) and tire pressure, coolant level, oil level, belt tension and belt condition, battery and terminal condition, lights, wipers, heat / AC, power steering fluid, windshield washer fluid, and cruise control operation. There are other things but i think you get the jist of it. I have never been left stranded and don't intend to start out with any unknowns about my vehicle. Sure things can happen to anyone on the road but being confident in your vehicle's ability to safely get you to your destination is extremely important to me. If you do not trust your car, renting is a good idea since they will also send help if you do get into a jam.
