you will def want your ac in tip top shape. it dosn't cool down til the end of october. i have made the trip from ny to az several times in my toy. not really a big deal. change the oil right b4 you go. either change the belts and hoses or have some spares. maybe plugs, wires, cap and rotor. rear dif fluid and trans fluid if they have never been done. about all you can do.....
