Greetings & Welcome!
Safety is relatively easy, just never be anywhere that is isolated, and always keep your doors locked while inside, even while driving.
While I have had break in attempts while in town, as soon as they discovered there was someone inside, they ran the other way.
Boondocking is whole different story. I have been robbed by both gangs and individuals while boondocking. Even 5 of us weren’t enough to hold off a gang of thugs with guns. The more isolated you are, the more vulnerable you are for the bad guys. I will no longer boondock unless it is with a large group of 10 or more, and preferably with some of them carrying guns.
Even in town, I won’t park in deserted industrial areas or empty parking lots. I want other people close by if I get into trouble. As a woman, you are even more vulnerable, and taking unnecessary chances is not a wise choice. If I can’t find a place in town that I feel safe, I will go to an RV park and rent a space. In some towns, the whole place is sketchy. If not tied down by a commitment, I will move on the next day.
I keep a spray bottle of vinegar in my van for cleaning, and another small travel size spray bottle of it in my pocket. Vinegar in the face of a person, a dog, or even a bear will stop them almost immediately. It is legal everywhere, and effective, but not lethal. Other types of legal sprays can work as well.
