Eastern Montana to Southern California, do I do it?

I’m debating on driving our Tesla Model S down to California for a family trip. Our Model S is NOT long range. It says 220 miles when charged to 100% but I’ve never pushed it to see how accurate that is. The hard part would be from Montana to Utah since there’s not a lot of charging stations a long the way. We’d be going about 140-150 between each one. Is that too risky? I get so nervous about getting stranded. Has anyone actually ran out of energy before your destination? We’ll also have 2 children with us so that makes me nervous as well.
