You are insane to drive something that uncomfortable and unreliable that far. Get some earplugs. Rub some soap in the gas tank holes. You can't hear the radio in a 40 anyway. Bring lots of ducktape. Skip the power inverter. set up a 12v plug and get the cords to charge phone and computer directly from 12v. take lots of pictures.
I'm awaiting the trip report. Jealous that I can't go too.
