I'm crazy enough to drive my bus to cali for such an adventure, but i'm not sure if your budget could afford to pay for the fuel. I'm also from michigan. It's only 2,500 miles from here to LA. My bus isn't really that old though, it's a 1991....and it has a full size jacuzzi inside. Not sure how that would fit into the script....
