I stopped and charged @ 2A yesterday. Or stopped and got nothing from 2A, so I went to 1A, which worked. Went to call Tesla, and none of the Superchargers had the printed telephone contact information attached to the little spot. After I got to Wichita, I called the Tech Service folks (contact telephone number was printed and available) about 2A status. Any two of the three chargers (OKC, Perry and Wichita) are valuable if you have an 85, or even a 70. Depending on weather and other conditions, a 60 might need them all. As OKC continues to fill in the I-40 route heading East, it is very valuable. Looking down the road a bit, as battery packs begin their decline for capacity, all three might still be necessary at some future date. And although it is not the Ritz, charging at any of the Superchargers is minutes compared to literally hours at an RV park (I have the T-shirt). BTW, the RV camper was still there yesterday along with about 5 fully-loaded big rigs.
