Excited about this SC! We just drove the Amarillo-Trinidad leg last week on our road-trip from Houston to South Fork, CO in our Model Y. It was the only difficult portion of the trip and we decided to modify our plans to stay at a hotel with a destination charger in Dumas on the northbound drive because we were afraid running out of juice in the middle of the night in NM. When this one is built, we won't have to take such precautions!
Regarding the number of stalls, I'm not worried. Clayton only has 2 operating gas stations, so the ratio of SCs to gas pumps will be great. On our recent trip we made 11 SC stops and never saw more than 3 cars charging (including us) at any stop.
