Might check the Pahrump area out on Blue Diamond road. Pahrump is about an hour from Vegas. We left there about 20 years ago and it was growing like crazy so I would guess they have storage lots there. When we were there we had what they call Ranchettes they are 1 1/4 acre lots and at that time there were few to none HOA's so if you can stand an hours commute I would look there for a place to live. I think its highway 160 and was a pretty hectic drive. Depends what side of town you want to be on.
when you do get settled think about getting your camper in in a under some kind of shade, the sun and heat will rough it up. We left a trailer uncovered for a summer the we were living there, it aged it pretty good. Every piece of plastic inside, sinks toilet switch covesr all turned yellow after one summer
Just a couple of things to check out.
