Preaching revisted
For the folks that say this doesn't matter:
In New York State and particularly on Long Island last fall a person put a 4000# boat on a 3000# trailer, the trailer detached and killed a bicyclist and hurt someone else. They have filed manslaughter charges against the boat towing person.
The news article is sighting the overloaded trailer (I don't know what Law enforcement is sighting). In the picture it looks like trailer simply wasn't hitched right in the first place and just came off regardless of the weight (or he had the wrong ball on the tow vehicle).
It may be prudent to engineer your towing rig for the job at hand and probably more importantly YOUR towing and experience levels. Knowing one is over recommended weights and knowing what to look out for and pay attention to in that situation, is far different than a novice being near the limit with a wife and two children distracting the driver while going to the state park, having no clue what could go wrong (and how quickly).
Snark away...
