Just join a KOA which has camps all over the USA. Then you get access to all their spots. Also truckers know lots of places to park and sleep with millions in cargo in the back. So get in with their networks. Find the industrial parts of urban areas and you can find places to park. near the ports or where trains are loaded with cargo. Lots of vans and trucks. Also any where construction is going on you can often get away with parking vans or trucks. Also don't make your camper look so campy. Make it look more like a work trailer from the outside or make it more discreet so you blend in.

Also, paying for a parking spot somewhere might be worth it. The idea is to CHASE the work. Wherever you can make the most money is where you should relocate your mobile camper to, park, and stack cash which you convert to gold and silver bullion and safely stash in safe locations.

You could just continue to live with your parents but get a job that requires you to travel a lot, which means then see less of you and you still have a room they let you come home to when you return from a week of traveling, driving truck cargo, working remote construction projects for a steel company or something, I know a guy who bought his own rig and just runs cargo for contract. He said there's bidding sites and he just bids and chooses which cargo to run, and then he says there's groups he joins but i guess it's 1099 work or he started his own business llc

There's one company my bud worked for that just repaired signs. They had repairmen traveling around different states installing large storefront signs and repairing others
