I didn't put my aero hub caps on just because I hate the way they look.
From San Diego to Grand Canyon, it was pretty painless - two stops of 25 min and 1 last stop for 5 min. Each stop was perfect for some in the car to use the restroom and we were on our way by the time everyone finished.
I planned out hotels and AirBnB's to have chargers available so each morning we had 100% charge while we were at Grand Canyon or Antelope valley. Going home from Antelope Canyon through Vegas seemed shorter since we stopped to eat dinner in Vegas. Since it was a longer route, we had to charge full 20-24 min at each stop.
Total cost for supercharging was $90. So for 1400 mile trip, it is not bad.
I also purchased 1 month of FSD and Premium Connectivity.
I don't think I will do FSD again. The standard autopilot is what I mostly ended up using because the automatic lange changes while on FSD was just so annoying to me. On a two lane freeway with trucks all lined up in the right lane, the car kept wanting to immediately go back into the right lane. I know you can cancel it with the turn signal but it was just annoying to have to keep doing it. So most of the trip, I was just using the standard autopilot. I get that you also won't get the auto-lane change but FSD isn't worth it just for that.
The premium connectivity was definitely nice to have for the satelite view and also streaming music when our phones didn't have reception.
Overall, I was happy that the trip wasn't as painful as I thought it would be. I thought we would have to stop a lot more often, wait around for it to charge, and passengers would never want to do a trip in a Tesla again. But everyone was impressed, and best of all, I was not NEARLY as tired as I would normally be for doing such a long drive straight through.
