Nissan Murano: Towing safety / Ball mount
The hitch ball is attached to the ball mount
and the ball mount is inserted into the hitch
receiver. Choose a proper class ball mount
based on the trailer weight. Additionally, the
ball mount should be chosen to keep the
trailer tongue level with the ground.
Choose a hitch ball of the proper size and
weight rating for your trailer:
The required hitch ball size is stamped
on most trailer couplers. Most hitch
balls also have the size printed on the
top of the ball...

whole amount of tongue weight and gross
weight directly on the ball mount and on
the receiver...
