I live in Pahrump in sticks and bricks. Actually we are not a city. just an area of Nye County. Every time someone wants to incorporate we shut it down. There is another dirt road off of 160 called Carpenter Canyon. it is on the South end of town. The dirt road goes East. There is a BLM fire station marker on 160. Down by Gamebird Rd. I camped there while looking for a house. I have not been all the way up but I hear it goes to a small creek. I could still see the valley from where I was, (road curves North and goesa behind a hill).
I went to Walmart this morning and seen a Class B that has been there in the lot for what seems weeks. Homeless people camp behind that shopping center as well, and the Police leave them alone.
For free water find Petrack Park, just West of 160 off of Basin. Across the park road from the community building there are bathrooms that are closed, but the spigot at the light pole is still on, (watered my dog there yesterday).
If you camp off of Bell Vista RD, (goes to Death Valley Junction), be careful to not be down stream from what us locals use for a gun range. it is about 8 miles out of town. Shooters point North west sort of. There are dirt brims that we shoot into, but someone may get careless.
