Whatever spare parts you bring, be sure to dry-run a road side installation. Even something simple like belts.
When I lost the alternator belt on the highway last year I had a replacement, but had never tested my toolkit to see if I could remove the AC belt. I could not, and was forced to cut the AC belt off to replace the alternator belt. It was a blazing hot summer day and the return trip sucked.
