We went from Grand Rapids MI to South Padre Island TX 2 years ago - 1,600 miles each way.
Adventures along the way included:
Drivers side wiper overextended past the window and the linkage broke during an overnight rainstorm
Jasons bus getting stuck on the beach for 3 days buried up to the frame in sand/sea water
Batteries nearly exploding and needed replacement at midnight
Ran out of fuel, took 3 hours to figure out how to prime my fuel pump
All and all it was a great trip, back when fuel was only $2.50 a gallon, 4 of us rode on my bus - total fuel/campground for 10 days was about $260 each person.
