This hardly happens to us ever fortunately :) but one cg I was right on the path to the spot where you put in the tubes for river rafting. omg the traffic and some came right under my awning and what I did was simple. I backed the truck in sidesways to the front of the camper and made it impassable and put the clothesline across another way from tree to tree and then put chairs etc in another area...it worked fine :) Never had a problem after that, most I would do is use the block system if I can....but you can't truly fix their manners.
