This is a classic example of the widespread problem in society today.
Boys will be boys, yes, absolutely. They will try stuff if they think they can get away with it. I got many a whack to the butt when I was a boy. And I learned discipline, manners and respect because my parents taught it to me.
However, discipline and parenting skills are the whole root of the problem. Kids today are not taught to respect other people or their property. When a child is allowed to run amok as a general guideline they will see nothing wrong with climbing on someone's new RV. No respect has been taught.
Pretty simple solution here. Take the child aside, teach him this is wrong. The swat on the behind and a short lecture should be all that's required, if the parents have any discipline habits with their son. This factor is an unknown.
Too many people want to ignore the real problem, parenting and discipline, and blame the ladder for being there to climb. Why make the ladder inaccessible? Just teach the child not to do it!
This is all too common today. They want to legislate everything and prevent people from a wide myriad of things instead of allowing common sense, cause and effect, action and consequences and the like, to prevail.
