I carry my jump box with compressor(won't start it but if you are close and just need a little extra or loose an alternator and need to keep the FSS open a few more miles also gives you an extra way to charge a phone in a pinch), a 4 way and a basic set hog hand tools when I travel. Couple rolls of tape and some zip ties are a must. A couple tie downs can be useful even as a tow strap in a pinch. Roll of paper towls and tp. I carry a bottle jack in the truck. I always have a qt of oil and a couple bottles of water too. Blanket or old tarp is useful again depending on the climate. Oh yeah, and my wife with her AAA card is never a bad thing. She travels by herself enough it's worth it.
Just remember, you can't plan for everything. Good general maintenance is really your best friend. If you've kept up the old girl, she probably won't let you down.
