Reporting back after picking up some friends flying in from Canada, and road tripping to Riverton/Thermopolis:
Starting from a ~95% charge in Laramie Friday morning, the plan was to pick up three passengers from the Denver Airport, then head up the I-25 all the way to Casper. Of course, best laid plans.... on the way out of Denver, we realized I'd forgotten my Bluetooth speaker. So, up the 287, back to Laramie, along with a ~15 min stop at the Laramie supercharger.
Getting into Casper by way of Med Bow, I stopped for another ~15 min stop at Hat Six supercharger that evening. On the road again early Sat. morning, got us into Riverton, for a guided horseback trail. Had more than enough charge for putting around Riverton afterwards, but I did charge to 95% again at the Riverton destination charger in the evening.
In the morning, we hit the road for Thermopolis, and spent most of the day on the rivers. Again, plenty of charge to putz around afterwards, including the hot springs. Charged again to 95% at Eagle RV in the evening.
The only wrinkle in the morning was one of my friends realized he left his eReader at the hotel in Riverton: so, back to Riverton! That meant our return route had to pass through Rawlins, and reversed our route through Laramie --> 287 --> Owl Canyon --> I-25. We did not another 15 mins supercharging in Rawlins, and then again in Loveland.
Tl;dr - I probably really overly conservative with the charging and range, and probably could have spent less time supercharging especially if we hadn't forgotten the Bluetooth speaker and the eReader. The lowest charge I had the entire trip was I think about 14% pulling into Loveland. Despite the mid-Wyoming desert of superchargers, we probably would have been more than fine with the Level 2 options. But even then, the supercharging didn't add a huge amount of time to the driving. Overall, range was more than sufficient, at least for this spring/summer driving, and everyone had a blast!!
