When I was in Niland, CA during my trip near the Salton Sea, I looked up some places to stay other than my car. I wanted something different for a night or two, just to change things up. I actually some AirBnB’s for $10/ night. They turned out to be just some tents that were set up by some off-grid people.
For less than the price of two nights at their “hotel”, you can have and own a similar one from Walmart.
