Did those 10k-12k mile cross-country jaunts a few times in my 2013 MS85, before the Supercharger network was well-developed. Took a bit of creativity to charge, and luckily not in any hurry. Loved the Alexander Graham Bell museum in Baddeck NS, where I charged in a boatyard.
Can't wait for a NACS-CCS adapter for my Kona, but the MS85 with its free charging still rules for long trips.
navguy12, have a great trip, and perhaps consider an air purifier running off a small inverter to deal with forest fire smoke.
