not real worried about my first trip just a weekend 40 mile up the road, but trip #2 is 1000 round trip, besides the spare, jack, screw driver and rat set, basics "WHAT DO I REALLY NEED TO TAKE TO FIX...
Jack torque wrench correct socket for lug nuts screw drivers pliers wrenches brake spoon cordless drill covers probably 90% of your needs. To that I do carry a combination wrench set and lots of misc screws.
