This is the definition of easement that I found on the web:
n. the right to use the real property of another for a specific purpose. The easement is itself a real property interest, but legal title to the underlying land is retained by the original owner for all other purposes. Typical easements are for access to another property (often redundantly stated "access and egress," since entry and exit are over the same path), for utility or sewer lines both under and above ground, use of spring water, entry to make repairs on a fence or slide area, drive cattle across and other uses. Easements can be created by a deed to be recorded just like any real property interest, by continuous and open use by the non-owner against the rights of the property owner for a statutory number of years, typically five ("prescriptive easement"), or to do equity (fairness), including giving access to a "land-locked" piece of property (sometimes called an "easement of necessity"). Easements may be specifically described by boundaries ("24 feet wide along the northern line for a distance of 180 feet"), somewhat indefinite ("along the trail to the northern boundary") or just for a purpose ("to provide access to the Jones property" or "access to the spring") sometimes called a "floating easement." There is also a "negative easement" such as a prohibition against building a structure which blocks a view. Title reports and title abstracts will usually describe all existing easements upon a parcel of real property. Issues of maintenance, joint use, locking gates, damage to easement and other conflicts clog the judicial system, mostly due to misunderstandings at the time of creation.
IMHO the SOB has no right to park anything on your property or even in the easement for that matter. I believe that is one reason they make 8 gauge barbed wire. I would be putting it up along all common boundaries with your "neighbor" and on both side of the road access easement. Best of luck.
