I should get delivery of my S in November, and plan on driving it to our winter place outside of Tucson in late December from Northern California. No problem getting across Calif but the stretch from Palm Springs/Blythe to Tucson is beyond the probable range, at any speed. So far my plan is to spend the night at a KOA site in Blythe, do a Range Charge overnight, then carefully (slowly) drive to Tucson. I'm not thrilled going 50mph on I-10, as I'll be a hazard to the 80+mph flow. Any ideas on getting quick charge in western Phoenix area? Will sure be nice if/when they put in a SuperCharger station someplace out there.
