Coupling To The Tow Vehicle
Bri-Mar 70
• Unlock the coupler and open it.
• Before extending jack, make certain the ground surface below the
jack pad will support the tongue load.
• Rotate the jack handle (or crank) clockwise. This will slowly extend
the jack and transfer the weight of the trailer tongue to the jack.
Raise the trailer coupler above the tow vehicle hitch.
4.2.8 Gooseneck Trailer with Ball Coupler or King Pin
A gooseneck trailer with a ball coupler on the trailer connects to a
gooseneck ball that you must have installed in the bed of the tow vehicle.
See figure 4-8. A gooseneck trailer with a king pin on the trailer
connects to a fifth wheel that you must have installed in the bed of the
tow vehicle. This system of coupling a trailer to a tow vehicle permits
the tow vehicle to turn to sharper angles than are permitted by a bumper
hitch system. A gooseneck coupler consists of a tube in an inverted “U”
shape and a gooseneck ball receiver. The operation of the gooseneck
trailer is the same for the ball and king pin attachment with the exception
of the hitch connection. See your fifth wheel instructions provided by
the manufacturer for connecting, disconnecting and locking information.
