Inexpensive Curb Appeal Ideas?

Here is what the front of my house looks like. There is a trailer back there that no one can see (behind the camper and vehicles). So everyone thinks that my drive is the neighbor's drive and parks in our driveway or we miss out on things (for example: when the trash department distributed recycle bins, they passed up my property all together).

I would need cheap/inexpensive ideas to make my property look like it is separate from the neighbor on the left in this photo.
Thank you ahead of time!
