Tripping across the Mojave on I-40

I live in Barstow and have traveled east many times that time of the year. Out of Barstow to go to the Grand Canyon you take I-40. You can spend the night at the Wal-Mart parking lot if you so desire. It cools right down at night in Barstow to where it is comfortable. I myself would not go through Needles to get to the Grand Canyon. I would get off I-40 at the Goffs turn off into old highway 66 to highway 95, then from their drive to Laughlin and cross over to Bullhead, Arizona where gasoline is very cheap in comparison to Needles. About a dollar a gallon difference. Then from Bullhead or Laughlin go east I believe it is highway 68 to Kingman, Arizona where you will get back on I-40 which you stay on until you get to Williams, Arz.

The cut through Laughlin will save you about twenty miles instead of going through Needles.

If your coach is in good condition you should have no problems over heating. The only climb you will have is when you leave Laughlin or Bullhead for about twelve miles, but you can leave early and you should be alright. Done it many times with no problems.

Do not take I-15 because it would take you to Las Vegas and about 90 miles off.
