We did Flagstaff to Blanding - 243 miles which is a little bit longer than Holbrook to Blanding. 2015 S85D.
Needed to go slow for a bit. Yes, some range anxiety, but made it. Hotel in Tuba city has a 240 destination charger if you want to kill some time and get more juice, but it is just faster to go a little slower - 65 mph.
Kayenta would really be a welcome addition in that area.
