The following reflects my opnion
In the not to distant past you would go into an RV Park, setup, unload and enjoy your stay without worrying. You could leave your chairs, bicycles, coolers and whatever else outside unsecured without fear of them being stolen. Lately I have noticed more "permanent" residents as the RV Parks begin looking more like trailer parks. The mangers care only about filling spaces. People walk through your site, make noise all hours of the day or night, leave theiir sites looking like a "junkyard" and the park owner/mangers say nothing. We have noticed more "workmen" living in inexpensive "trashy" looking RVs. More people have found it is cheaper and less regulated to live in their homes on wheels and if they get complained on too much they just hook up and move on to the next park down the road. The RV park are less secure and seldom do you see any law enforcement presence in them as you would in a sticks and bricks neighborhood.
We in the real RV community must demand owner/mangers of RV parks enforce their rules and we must report violators of said rules to the management. Then let the management know if they will not make their parks more secure you will not stay there and will pass the information about that park to all of your RVer friends.
I must say the park we are staying in is the exception to the rule as the manager is very vigilant in making sure the "residents" have a safe and seure environment so we can enjoy our stay. This park is clean, very well maintained and we feel safe here even though the park is not is the greatest area. I guess the bottom line is we are all responsible for our own safety and if you pull into a park and it looks and feels unsafe then we should 'go on down the road'.
As far as storing your RV you must find a storage area that is monitored and patrolled. Don't leave valuables in it while in storage (or leaving it at a dealer for repair).
May we all have a Merry Christmas and a safe secure New Years...Happy Travelling...
