Towing Hitch Height Adjustment

Rosscoe,
You should aim for being level when fully loaded and hitched up. It really is trial and error but as long as you don't have too much weight on the towball your torsion bars should take care of it. With the heavier springs you should get less sag than before to start with.

Rosscoe,

When you adjust your coupling height be very careful not to have it too high.

I am not an expert about all the physics involved but I do know, from a rather scary experience that if you get it wrong the van will drive the car. I once loaded a box trailer with the aim of avoiding the back of the tow vehicle being too low. This meant that the weight was not evenly distributed ie too much at the rear of the trailer. This was OK until I was heading down a steep downhill with the right foot off the throttle, it dragged the car all over the road. If I baked it got worse and I was to scared to accelerate.

I know you are not talking about reducing your ball weight but simply having the coupling too high could have the same effect. For example if you are moving a loaded trailrer by hand it is easier to lift once the coupling gets above a certain height, usually horizontal. THis is because gravity allways pulls vertically down if the coupling is too high then the centre of mass is moved towards the rear of the trailer and this could casuse problems.

Like I say I'm not an expert buyt I do know how scary it is when the trailer takes over.
