So far, the only RV related close call we have had was last year in the KOA CG in Williamsburg VA. One evening at dinner in our little pop-up camper, we heard a huge gravel scraping racket. By the time we realize it's not just someone dragging a plastic water container or some such through the CG and go outside to see what it is, this large brand new MH makes the turn between rows of sites perpendicular to ours and heads up the hill (we are on and outside end site at the bottom) dragging a damaged car on a tow bar behind it. It's just sinking in to my mind that he has torn the whole front end half way off the car by turning too sharply for flat towing (noise was the end of the bumper dragging gravel) when he turns back the other way into his site. I hear a POP and the noise changes when the car separates form the MH. Myself and a few other campers sprint up to the car to attempt to secure it, but it's already rolling backwards down the hill with too much momentum, so we have to step outta the way and let it go --- headed directly for our site! All I could do was stand there and watch thinking "Everyone's out of the camper and I hope insurance will cover what is about to happen...." As the free rolling car crosses the perimeter driveway, it wiggles on a ripple / rut and steers itself slightly to one side, missing all of our stuff by about 5 feet and parking in the ravine next to our campsite.
All of this happened with the CG employee "guiding" the MH to their site - I guess he could not hear the racket that brought people out of there campers all around.
I walked up to the MH owner and looked over the radiator core support (part of the structure of the car) with the bumper still bolted too it all still hooked up to his tow bar. Then we looked over the car in the woods. You could see where the uni-body of the car had been bent back and forth and ripped apart from turns. The poor guy was dumbfounded. He said this was his first trip with the RV to celebrate his retirement after a full military career. The guy asked me if the hitch failed and I told him "no, the car failed....I'm afraid your gonna have trouble getting any warranty on that"
