The use of a single chain is also a dangerous thing to do and can lead
to an uncontrollable trailer swinging wildly behind your vehicle, or
worse tracking off in another direction throwing your vehicle out of
control . Trailers should all have TWO chains for this purpose, and
they should cross under the tongue in an X fashion . In the event that
the trailer should seperate from the vehicle the tongue will fall onto
the crossed chains and not the roadway , this keeps the trailer
tracking straight behind the tow vehicle . It prevents the tongue from
digging into the ground and last but not least it keeps the tongue of
the trailer from going up too far under your vehicle .

A number of safety chains sold on the market only have a single hook on
the end of the chain . This hook can fall out of place on rough roads
so a hook with a "gate" on it , or a different style of clasping
mechanism is prefered. Make sure that your chains can not contact the
road , this is especially inportant on gravel roads because the chains
can cause stones to fly up onto your trailer.

If in doubt contact a RV Dealer or a Hitch Shop .
