Would just like to pass this info along to the stealth campers out there. You can go to any large Industrial complex like a power house, chemical plant, refinery, mine, mill and blend in by parking in the construction parking lots. I have worked in a lot of plants and everyone I ever worked in had separate parking lots. One lot will require you to go through security or have a sticker on your windshield. This lot is usually for the plant employees only. The other lot is for the temporary tradesmen (iron-workers,boilermakers, millwrights,labors, electricians ). Many times during a large shutdown there could be hundreds of workers working around the clock. I have slept in these lots before with no problem. And this was with no stealth at all. The parking lots are usually well lit and there is security near by. Occasionally there are porta johns set up outside the gates. And best of all no one knows who is who and you don't have to pass through security to park in the construction lots. Now obviously this isn't going to work all the time as construction isn't always going on in that particular plant all the time. One thing about this option is that there is no shortage of these type of plants around. They are in the city's and out in the country both. All across the USA. Don't be intimidated by all the fences and security just drive around till you find the construction lot. They usually will have large signs letting you know that THEY are not responsible for theft or damage to your property or it will say park at your own risk. When you see this sign you know your in the right spot. Just park on the outskirts for a good nights rest. I imagine you could go undetected indefinitely assuming there are other cars parked there all night. Finding a plant to park at will be fairly easy just look for smoke stacks. Hopefully this puts another wrench in your toolbox of places to stealth park.
