We are in Henderson Nevada, about 60 miles from Pahrump and the smoke is often so thick you cant see across the valley. I should go to Pahrump!!
Anyhow, we just got back from Pioche Nevada and there was plenty of smoke there too. It is a small town historic town. The RV park we were in has several folks that are there for months at a time. It's called Pioche RV Park. Real nice sites, all back in. In fact, you back in all the way from the road, not much maneuvering area. Wide sites (plenty of personal space), full hook ups, and deer come by to say howdy each evening...and probably morning too if you get up early enough.
Drawback is that it is in Lincoln County where there are, among other things, no major grocery stores. There is a small grocery in Caliente, about 20 miles away.
It may be further than you want to go, but I thought I'd throw it out there.
I hope you are safe from those fires, and wherever you go, be safe!! Happy trails.
