Guys it's already been said here,
but take it from someone who has crashed while pulling a trailer,
make sure that chain is wimpy enough so that it breaks,
and the trailer goes away, far, far away!!!
I went over the handlebars and rolled like a log,
my wife held on and finally let go when the bike went down,
she would have been run over by the trailer for sure.
What does a trailer do when the bike goes down and stops suddenly?
most likely it keeps pushing and then jack knifes, not a good scenario.
In my case upon impact with the Elk, the front end of the bike went up in the air like a wheel stand,
that's when I flew over, at the same time the hitch and chain broke and the trailer went into the ditch
