Hi,
Here are a couple of thing that may help. I have two Scotties Dogs that think they are German Shepard's, any thing that is not normal at night in the camper/at home, they start barking like crazy.
If you don't have dogs and you are a woman that is camping alone you can hang a picture of a dog on the outside of your front stone shield (like I have on my TM) and get a BIG dog bowl and leave it outside, (no water in it) that might attract other animals. Also get a size 13 men's boots (used and beat up) from family or some second hand store and leave them by the steps coming into the TM.
If I was a bad guy I would get the heck out of your area.
Dave
