I was lucky to get hiking permits for Havasupi falls in April, however after looking at charging options I don't think it is possible to take my Tesla from San Diego. One option is renting a car for 3-4 days in Laughlin or Bullhead city. Has anyone been there? Is there at least a 110v outlet anywhere near the parking area? With a trickle charge over three days it would be enough to make it back to Kingman SC. I took the Tesla to the Grand Canyon 3 years ago and it was a mistake as traveling with 3 adults and an infant it added about 4 hours to our trip and didn't make for a happy wife. After charging in Kingman we had enough charge to barely make it to the canyon however had to stop at hotel and use destination charger for 2 hours to make it to Flagstaff which was another hour out of the way.
