Interesting discussion. We just got a 60 a couple of months ago and the first thing we did was take a road trip from San Diego to Santa Fe. Went fine. Were able to charge twice during the day (lunch & dinner), eliminating a 'wasted' stop. A couple of others were conveniently placed at needed bathroom stops. I figured it added maybe an hour each day. Our only complaint, if you can call it that, was the seeming lack of restaurants other than well-known chains, mostly fast food. We're heading out for a San Diego to Atlanta trip tomorrow and I'm going to keep a log of our charging experience. What could possibly go wrong?
