The car is practically brand new. Shouldn't need any 'preparation' except the normal check the tire pressures, the spare, do an oil change if it is due - just normal maintenance.

>>I just don't get it, if this is a mexican city why it shows in a US map all the time?. <<

It is just across the border from El Paso -- not sure why google maps would list CJ instead of El Paso

I-10 through El Paso is within a mile of the Mexican border for a few miles. The trip from Tempe to Miami will take 3.5 to 4 days of steady driving (8.5 to 9.5 hours per day).
With 9 hour days your stops would be Fort Stockton TX, Lake Charles LA and Tallahassee FL.

thank you for your replies.

I got curious about your Ciudad Juarez question. Here's what I think, after bopping around on Google Maps a bit.

Firstly, the map you're looking at is not exclusively a US map. It's a map of your route, centered on the page, with considerable extra map information to the north and south of your route. And as it happens Mexico is to the south. So what? Google doesn't care.

Google very likely has given its computers some rules about which cities show up on their maps based on their population and the resolution of the map. Because of the length of your trip, the resolution is pretty low so that your entire trip fits on the page. I was able to get El Paso to show up by simply generating a much shorter trip on I-10 through that area.

There has to be another rule about twin cities because a lot of cities smaller than El Paso are on the map. But they're not right next to a much larger city. If you pull out to show the whole US, Minneapolis-St.Paul shows as just Minneapolis and Dallas-Fort Worth as just Minneapolis.

Correction: Dallas-Fort Worth as just Dallas.

Hi again, I am planning our route and which cities we are going to sleep at, we are planning to stay every night in a hotel, I am not really fond of driving at night, it makes me really sleepy even if I am just the passenger. For the first day of driving I thought we would stay the night at Amarillo, TX, the route shows Albuquerque on the way so we are stopping there just to take some pics. Then this is where I need help, we are thinking to stop somewhere in Mississipi, is Jackson a good place to stay at or is there any other more interesting place?and do you have any suggestions for the third stop? any tips will be welcome

Going through Albuquerque and Amarillo takes 3 more hours behind the wheel than the route through El Paso.
I don't think Fort Stockton is any worse than Amarillo.
On the east side of Texas either stay in Beaumont or Lake Charles Louisiana. If you really want a stop in MS, try one of the casino/hotels in Biloxi.

Google maps does not show Albuquerque or Amarillo on that route.

The shortest route goes south to Tucson, then east thru El Paso, San Antonio and Houston and takes 34 hours. If you intend to do this in 3 days and don't want to drive after dark, you aren't going to have much room to stop and take pictures or deviate from the shortest route.

Amarillo is 10 hours from Phoenix. Jackson is 12 hours from Amarillo. And then Miami is 14 hours from Jackson. So taking that route and making those stops means your days of driving would get progressively longer, which is the opposite of what you'd want. It makes more sense to start with the longest day while you're fresh and get that out of the way.

Juarez shows up because it is much bigger then El Paso.

thanks everybody
last year we stopped to sleep in New Orleans, San Antonio and Albuquerque and in reality now we wanted to stop on other places but you are right we don't want to take the longest route either. Any more suggestions on the cities to stop?

Tempe to Fort Stockton = 9.5 hours. http://www.booking.com/searchresults.en-us.html?aid=336408;label=fort-stockton-DdEk5zJHfWhV8cFoz0Rr7AS28297499248%3Apl%3Ata%3Ap15%3Ap2%3Aac%3Aap1t2%3Aneg;sid=95c2570943d3d0ef369a59e5a674271b;dcid=1;city=20128109;redirected_from_city=1;src=city
Fort Stockton to Lake Charles LA = 9.5 hours
Lake Charles LA to Tallahassee FL = 8.7 hours
Tallahassee to Miami = 7.5 hours

Tempe to Ozona, TX is about 11 hours. Sonora, TX is about 11.5 hours. I think you need to make it at least that far the first day if you want to complete the trip in 3 days.

Biloxi, MS is about 11 hours beyond that and has plenty of lodging options. Or you could go a bit further to Mobile which is about an hour east.

Now, if you mean 3 nights, so you actually have 4 days to drive you can back off a bit on the mileage.

Yeah, sorry, I meant 3 nights
