The neck of The Fifth Wheel is adjustable in height at two places.
Hand at the connection with the trailer. With bolts through the neck the height is set. Adjustment is possible, so that the Fiftwheel can be linked behind several pick-ups. With a closed trailer the neck is fixed at one hight. Mit einem geschlossenen Aufbau ist den Hals fixiert.
Also, the coupling itself is adjustable. On the pictures you can see how it looks.
