Just did this trip back in October. We stopped in Mojave, Lone Pine, then spent the night at Tom's Place before heading to Mammoth. Sounds like you will do the whole thing in one fell swoop. Use the route planner recommended above. Also, a couple things I found on my drive. We had some fierce headwinds on the 395 that dropped my consumption from the normal 250 wh/mile down to 325 wh/mile. That combined with your projected fast driving could be an issue. This is totally doable, but you just need to make sure that you have sufficient reserve should that happen.
In the morning at Tom's Place before heading into Mammoth, the outside temperature was 22 degrees. Car had frost on it for the first time ever! We had plenty of juice for the 25 miles to the Mammoth Supercharger (we went on to Reno) but did get the snowflake that indicates regen either wasn't available or range was impacted due to cold battery, not sure. That drive from Pasadena to Reno (2 days) was my longest trip yet. Long range 3 but no dual motor.
Be sure and stop at the Indian Wells brewery to stock up for the Mammoth Party!

These are the routes and stops I’m planning for. Is there a supercharger in Mammoth or more of a ChargePoint type facility? Where is it located? It would be nice to have a charger in Bishop as well to account for the last leg. Thank you for the feedback.
