I'm about to embark on a roadtrip next week in my 60kWh Model S and full family of 5. My wife is very concerned about making it from Barstow to Vegas. Can anyone tell me about potential places to charge between these two points if it looks like I'm not going to make it with a full range charge from the Barstow Supercharger? I've tried searching for RV parks between these two points but I can't find any. Don't know if I'm just using the wrong resources. Thanks in advance!
