The Dyrt app shows that the park is at the gas station, but there is a rundown sign on the edge of the lot indicating that the RV park is further down the dirt road (not straight past the gas station but to the right). You register in the gas station for $12/night. Not at all bad for what you get. 30 amp, water and sewer hook ups.  No other amenities. No 50 amp.

Follow the washboard dirt road down and you’ll find 18 sites with some pull thru for large rigs. There is a cement gazebo with a couple of chairs and tables in the middle of the loop. Freeway is on one side and nice mountain/desert view on the other. 

For $12 a night with hook ups it is hard to beat. Good place to pull off for the night. Appeared that there were a few residents there but did not feel sketchy or unsafe.
