Just looked at PlugShare starting in Nebraska and on to the East. You will have no issues. Really.
Wife and I have done a Cape Cod~Tucson AZ~Cape Cod run five times since 2019. First time (just the Cape to Tucson) in a Chevy Bolt (don't even think about it...), the others in a Tesla model Y.
Couple of suggestions. The fastest way to travel in an EV is charge up to around 60% at stops and drive the car down to as low as you dare for the next stop. I said this was the fastest way, not the smartest. We like to keep around 20% State of Charge (SoC) in the battery when we get to the next Supercharger. Makes us feel better.
Superchargers are very reliable. Never had one go completely down on us in around 12,000 road miles of EV travel.
We drive at a moderate speed (never over 75mph). Some folks like to zip along at +80. Well, "your mileage may vary" as they say. We (wife and I are pushing 80 yrs of age) like a relaxed trip and the extra few mph really don't amount to much time saved. For example, our normal Cape~AZ trip is done in six days. Some guys can do it in three! No thanks.
You have a beautiful car. Enjoy the ride, by the end of the trip you'll be a pro at EV road travel!!
