Alright, so I'll replace the ignition switch before the trip! I've had issues with it suddenly losing wipers and turn signals, and then coming back if I wiggle the ignition switch under the dash so a new one sounds like a good idea. I do have USAA, free 200 mile towing so I should *theoretically* be okay if something truly goes wrong. I'll have fluids and an actual floorjack, and a jerrycan to prevent getting totally stranded as well. Thanks for all the feedback everyone, I'll keep you all updated!
