long road trip
As Jay Leonard mentions, coolant problems on the road are the thing to look out for and I can atest are expensive as well. Don't know your mileage but I had the water pump fail at around 350k miles. I will not run the other trucks I have past 300k before a change out. Had a tensioner idler part fail around 200k once because the arm was getting bad and another time because the idler bearing failed. You can get a new idler assembly and ride it for insurance. Take a new fuel filter with you. I carry two. Spare fuses, a quart of oil and some steering fluid, spare tires and let her rip. You simply can't anticipate everything. If you have done the routine maintenance on shedule all should be well for that short of a trip.
Good luck on the move.
