Some months ago there was a thread which I cant find in which there was fierce debate of the merits of either.
I contended and still do that Polyairs dont and cant level a car with a van hitched up.
There was a poster who argued the opposite.

In issue 128 of Caravan & Motorhome on page 168 there is an article regarding this. The end of it all is that it supports my argument. The paragraph at the end of page 171 sums it up.
In the article they used a Landy ( whyever for) with self levelling suspension which does and can level itself via front and rear airbags.
The last paragraph states that it would not work nearly as well with AIRBAG ASSISTED as the front springs would prevent the height returning back to normal.
There are also graphs to show the effect of before, hitched without and with a WDH.
I rest my case
