We are full-timers in a 36 ft Class A with a Cherokee Trailhawk tow. We were here for a few days in mid April. The gravel road is rougher than it appears to the eye. We camped in the large area on the West side of the road a short distance from the trailhead. It was very windy the day we arrived, with wind speeds of 28 mph and gusts of 45 mph. 

AT&T coverage showed 1-2 Bars of LTE service, but I was unable to get a connection without a booster. We had an unobstructed view of the sky and so we were able to receive all 3 SW Dish satellites and Starlink had up to 12 MB/s. We didn’t try to load any OTA channels.
