I live in Safford approx. 155 miles east of Phoenix ( U.S. 60 E. through Globe then continue on U.S. 70 E. ) but there are no high power charging solutions out here with the exception of campgrounds etc. which can be hit or miss. One would need some pretty hard core planning to make the trek to El Paso along I-10 corridor. It's doable but would likely add day/s to your trip.
