Hello Everyone! I am planning my summer vacation from Dallas to California for the 3rd year now. Each year I hate the struggle with the uphill climbs through Arizona and California. I am thinking of a different route but am not sure if its going to make a difference or not? I normally take I-20 to I-10 all the way. I see another route on I-40. I used to go back and forth from Dallas to California a lot when I lived there 20 yrs ago, but I don't remember all these up hill battles!! Maybe it was because I had less people in the car (2 then as opposed to 6 now!) I would just like to have less wear and tear on the car if possible. Any suggestions or comments appreciated!! TIA!!
