New owner, MS75D. Using Go Anywhere Tesla, A Better Routeplanner and EV Trip Planner give very different results. The trip is only 146 miles (245km), but elevation change is +3500 ft (1000m). EV Trip Planner is the only app that shows I can make the trip (at reduced speed) without a long detour south into AZ. Two adults and luggage...I used 500lbs as extra load. Anyone have experience and advice with this route? Can I make it on a single 100% charge out of Kingman?
