Fit an N70 towbar to your N80 but try and source the aftermarket side brackets that lift the towbar higher or make your own.

Heres an N70 towbar on my N80 for reference. Sits much higher than the genuine N80 3 tonne towbar.

I decided on the kaymar rear bar/step/towbar for the exact reason that the standard towbar sits too far below the factory step for my liking. This one also allows for swing away carriers when i want to go on extended trips out west.
