A great way to travel in your RV and enjoy a particular place for a little while is to find caretaker jobs. This is when you are able to park your own RV on private property at no cost and perhaps even get paid for it. You provide security watching over a house or business while the owners are gone. Maybe you're looking after animals or maintaining something around the house.
Check for ads in newspapers, publications, online groups, etc. Check with real estate agents, security companies, schools, churches, construction sites, repair shops, storage lots, any place that might attract problems if no one was around. Maybe they have a high dollar place that could use someone parked around back looking after it. Perhaps you'll get paid but keep in mind that just a parking spot is worth something. The best deal is if you can get water and electric. You have it made right there. If I wanted to stay in an area, I may just offer to do it for free to get the private parking place. Even if you paid a dollar or two a day, you are still well ahead of a campground.
In down economic times, and if you can afford it, you could help someone out by either paying them a couple dollars a day for space or by doing a needed chore around the property. This will work best in small towns and farm areas, probably westward from the Midwest. It's more difficult in urban and densely populated areas like the east coast.
Make friends and help out. You may just meet some really nice people and establish long term relationships by doing this.
Use common sense and keep yourself and your RV clean. No one wants to bring a garbage pile onto their property or have more to clean up after you leave. Keep a clean site. It may lead to more opportunities to return in the future or references with people they know in other cities. It helps to NOT have a barking dog with you. I probably wouldn't want someone to bring their noise into my neighborhood or on my quiet farm either.
Have you done this and do have any tips you'd like to share with others?
