Thanks for the informative post. I need some help from your experience.
I have a X90D and live in Crossroads, Bellevue. I am planning to visit Leavenworth (through Snoqualmie Pass) this weekend with 4 adults, one baby and stuff for the weekend. If I start with 240 miles rated range, do you think I can make it?
Unless you are planning on taking advantage of Ellensburg SC why not WA-2 (with Monroe SC on your way)? It is actually shorter of a drive but with more turns and possibly slow vehicles. Assuming you can top up in Leavenworth either way should be fine. If you have a CHADeMo adapter then there are multiple opportunities to power up. However, because of skiing season DO NOT expect to be able to use the chargers in Stevens Pass or Snoqualmie Pass Chevron.
