So Paint Gap 4 is the last campsite on the road and it is a very narrow, rocky and rough road to get back to it. You will get your vehicles paint scratched getting back there. It is in a valley between two hills which means you get shade in the morning and in the evening but it also acts like a wind tunnel and magnifies the wind blowing through the valley. There was sporadic 1 bar 3G service from AT&T that allowed you to send a text but no phone calls or app/internet usage. Verizon had zero service. The spot is not level so if you are sleeping in a RTT or a vehicle make sure you have leveling blocks so you can sleep flat. We stayed here one night and it was very peaceful and a great sunset view. The wind shook the roof top tent all night but it wasn’t horrible.
