I’ve only had one incident where my gut told me something was off. I was in Canada in a Walmart parking lot. It was mainly empty, just one other RV and a group of cars in the far corner with young kids hanging out. I started to hear yelling followed by honking as the people in the cars wanted to make the RVers unwelcome. I followed the example of the other RV and left. I continued on until I reached a truck stop that had an area for RV overnighting. I checked inside just to be sure and then settled in safely for the night.
While startling and inconvenient this was a minor incident because I made the decision to relocate and not to stay. Beyond that, my experience with traveling in the RV for the past two and half years has been overwhelmingly positive. I don’t take that for granted though, I take precautions and have put in place a few “just in case” measures.
