I wasn't in an RV, but I was living in Brooklyn when Sandy came. Within 24 hours of her anticipated arrival, they had shut down all the bridges and tunnels. I very much doubt ferries were running, either. Family was calling me suggesting I consider leaving the city. I told them I couldn't even if I was to try.
For the record, my neighborhood fared well. I only lost my cable. Oh, a severed tree branch crushed the roof of my pickup truck. Subway lines stayed down for a while after that.
Also of note, I was impressed with how people most people coped in the aftermath. Those with power and water and such, shared it, for free. They ran extension cords out of their places into the street so people could charge cell phones. I didn't hear of any looting, gangs running wild in the street, etc, while there certainly was opportunity for such antics. There was a police presence, but they were concentrated into areas of the city that were hit hardest, and I suppose most susceptible. But that led me to observe in my neighborhood hardly any police presence at all, which is unusual. Except, of course, some lone bitter meter maid or something that ticketed my pickup with the crushed roof for having an "improperly displayed license plate", which was hanging crooked by one nut. The hardest thing was finding gasoline, which I needed for my work vehicle. There were some fights that broke out in lines at filling stations.
