Good luck and have a safe trip!

Fluids, a good, complete ratchet set, some wrenches and hand tools and that should be all you need. I like to keep a spare alternator (and power steering, if applicable) belt on hand as well. For the minimal cost, the grief and hassle it has saved me in the past is priceless.

Don't forget about us Northerners once you're enjoying the Cali sun!
