I am not paranoid, but that doesn't mean that everyone is not out to get me.
I think you need to make sure you have insurance, just in case. Don't leave anything of real value outside unlocked, don't leave anything of real value in plain sight and put a GPS tracker on your RV. After that, just use common sense. Once you get caught up in the "But, what if..." spiral you will not want to go anywhere. Sell your RV, get a place that is in a safe spot and you will live a more peaceful life.
I am not a full timer but I have been pulling trailers all over the western side of our country for more than 24 years. Haven't done anything stupid (yet) and haven't had any problems either. I choose to believe that life is much better than what an overactive imagination might come up with. Just my 2 cents....
