Which is cheapest route?

I am a fellow trucker moving from Georgia to my true home, California.

Im figuring i can take i40 for the majority of the way then at Flagstaff drop south to i10 to go into california.

For argument sake, im headed to Temecula, which is southern most part of Riverside county before hitting San Diego off i15.

I am driving my personal old vehicle that is a ford focus wagon 2002.

Yea don't need to say it but the good Lord blessed me with what i could afford at the time and i own it. But im trying to find the cheapest route because the cheapest means less uphill and im trying to drive on flat as much as possible and downhill as much as possible.

Yea ill be going California truck speed cross country with the heat on and windows down lol.

So can anyone help because i did drives recently out of California taking i10 and i40 but didnt pay attention to how it would be going west and not east. I hope i get a run soon to cali.

Moving first week of August this year in 2016.

Never found a FedEx contractor that might be out of Temecula or San Diego to work for so ill end up trying to live in Temecula so i can be fairly close to my children in north san diego and not too far from city of industry in cali.

All help is appreciated and i know the joksters will always say things.

God bless you all out there on the road and be safe.

 

Ok im leaving from La Fayette, Ga that is almost to chattanooga.

I agree if i left from Atlanta also. But my parent's house in La Fayette, Ga is where im leaving from and that is way up northwest georgia and its about 30 miles south of Chattanooga, Tn

 

I do have a Marine Corps. Buddy in Oklahoma off i40 that i thought about visiting on the way and stopping at Santa Rosa, NM for a swim at the Blue Hole spring.

But ensuring my car takes the easiest route may be the smartest thing. Ive recently driven i20 west and east and only remember in Louisiana the roads are super rough but my memory escapes which mountain pass is easiest on my car to go into cali from

 

Its not so much uphill taking i40 into cali? I thought about that route but thats where i need fellow drivers help
