Adjustable towball hitch (ATH) Vs WDH

They can drop or raise the trailer or caravan.

Adjustable Towball Hitch

Thanks Tony. It appears to be a hitch that can be height adjusted to enable the towed vehicle to be level.
It is nothing like a WDH and won't do the same job. The WDH transfers weight back to the front wheels.
This subject can go on and on. There have been pages and pages of comments on this subject on the Caravaners Forum.

I agree with Rod. They can't be compared as they do different jobs.

G/day Rod, I use one of these on my set up, I think you still need a wdh to take the weight off the tow ball and balance the rig, the tow ball should be the same height as the van when the van is level but unhitched, when you hitch, up and remove the dolly wheel the hitch will take the weight, ie.,ball weight, thats when the wdh is used to level up and transfer some weight onto front wheels.

Bugger, I thought I had saved myself a few bucks, now it looks like I might have to add a few more:)

Cheers

The others are right. The difference with a WDH is it is a lever, not a spring, spacer or anything else. When you lift the bars up and hook them onto your draw bar, it is like lifting the handles on a wheel barrow. You take weight off the rear suspension and transfer it to the front.

The WDH has to be a spring other wise the whole thing would be rigid.
The WDH does transfer weight but it also INCREASES the load on the ball not lessens it.
It lessens the weight effect on the rear suspension though.

If you put your hand between the coupling and the ball and then get someone to tension the WDH bars up. They will have to stop because of the noise.
