I'm in the very early stages of planning a road trip from Northern California to Walla Walla, WA this summer. I would likely not attempt unless additional Superchargers are in place by, say, August 31. And I don't have dual chargers, which really annoys me, I hadn't understood the importance of them in doing road trips when I configured last fall. In any event, I'm thinking of an itinerary that includes Portland, The Dalles, Walla Walla on the trip up. Then Bend and down on the return. Any tips would be much appreciated.
