New to Rv - questions about RV parking outside of campground

I saw a thread, not sure where, about a guy who had his slide out and it got hit by a car. He did not say where he was parked but I would imagine it was in a non-rv lot. Maybe if he did not have the slides out, he would not have suffered serious damage by an unlicensed, uninsured driver.

Think in that circumstance, leaving slides in is probably prudent.
