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.
X2 Take 93 to Vegas and Utah 3 times a year.
