The return trip on I40 may not be the way to go. The last time I drove from the Arizona state line to Flagstaff I had some the worst chuck holes I have ever seen. Because of the heavy truck traffic you are unable to avoid the chuck holes.
Maybe the road has been repaired by now. Perhaps someone who has recently gone the East bound route can chime in.
If you do the I40 route I recommend turning north at Kingman and take US93 to Las Vegas. It is a good 4 lane highway most of the way.
They are repaving I40 as we speak near Ashfork. If I am heading East out of Kingman I take old RTE. 66 to Seligman. (stop at snowcap for great burger). RTE 66 is a much nicer ride with very few grades and no trucks
