I am planning a short trip from Flagstaff to Antelope Canyon near Page next weekend. I ran the trip throug the Tesla, EVTripPlanner, EVTripping and ABetterRoutePlanner (yes, OCD kicked in). I get wildly different numbers from all those, especially for the return trip (Antelope to Flagstaff). I am a little worried as the final part of that leg is driving up a 7000ft mountain and I will have little chance to adjust my driving at that point. With a 100% charge starting in Page, I get between negative values (slow to 62), 17% remaining and 35% remaining. The Tesla planner is most optimistic but I really don't trust that one. Has anyone done this trip not driving a 100D? Very excited to see the Antelope Canyon and might make a detour to see Glen Canyon Dam but will charge at Page before we return to Flagstaff.
