...Other than land, area or territory of your own or under your control or one you have contractual permission for.
For 4 weeks? And for 3 months? More?
Putting something on a piece of land long term and prohibiting anyone to move it is effectively occupying that piece of land.
You only can occupy land that you either have legal rights to, or that encounters no objection from those who has (adverse possession). In the latter case, it's not that you don't "provide them right to tow", rather they just don't mind not towing it.
What you describe more resembles homesteading, but that is not possible in California.
