Can you send your route? It's extremely unlikely your route was out of supercharger range. There's good coverage on that route: https://www.tesla.com/supercharger
Superchargers don't have giant billboards advertising them, they are often very subtly tucked into a hotel or gas station. But they are there.
From Childress,Tx, we meandered SW towards Lubbuck, which we skirted to the north, then down a zigzag of roads to Denver City, Texas. Then from Denver
City over to the border of New Mexico to Riverside, NM. There are signs saying to gas up because of a lack of stations further up the road all along that stretch. Guess what that means?
There are superchargers in Childress, Plainview right to the north of Lubbock, and Post right to the south. But also that whole route is only 300 miles, less than a charge.
Can you send a list of these chargers? Also, we chose to bypass Lubbuck, our gas or if we had a hybrid would have allowed us to determine our route, not our battery charge.
