Vegas to Texas

I always take the middle route and avoid El Paso. Plus the view is better and their is nothing going through lower New Mexico may be a little cooler weather next week will be 105 in San Antonio and 106 in El Paso. There are also more places to stop and rest.
I think that is the route we will take. More stops/people/gas stations. There is a lot of nothing on the southern route, not a great place to break down. How's it been at night? We will probably drive 10 pm to 10 am ish, trying to avoid the heat with no a/c.
