We left the supercharger with a full max range charge of 197 miles of rated range. With 4.3 firmware it should be noted that the range will show 197 miles for about 10 miles of highway driving. I believe this to be a bug since ideal range on a full max range charge shows 226 miles. We planned a stop in Chico and were graciously allowed to charge at Sun Valley Acoustical from a Tesla HPWC at 40AMP! With several mountain passes we needed to stop again at Yreka where we wished we had a Roadster to Model S adapter as the first RV park we asked about charging wanted $20 for an hour of charge. Thankfully the 2nd RV park was much more reasonable at $5. We stayed for about 2 hours to get about 30 miles of buffer range to get over the passes. We looked up elevation maps to see that our destination was about 500 feet lower overall so it was great when we arrived with 2 more miles buffer range than we started with!!! This car is amazing! We stayed at the Roadway Inn right next to the Aerovironment charger at the Texaco station. Woke up to a free max range charge!
