Hi Yonnee. I was going back through some old postings in this fine foum and read your comments about the Al-Ko and knee suspensions. Would you be prepared to get back to me (and the forum) with a more detailed description of the latter (what it looks like, how it works etc) Many thanks. Derek.

Have a look at a Coromal caravan, they use Symonds Knee type suspension.

Yes, Coromal Caravans have this system as standard equipment. Also called the Symonds Knee Suspension, now manufactured
by Melbourne Trailer and Caravan Supplies in Chelsea Heights, Victoria. Basically it's an independent wishbone arrangement
with each control arm having two pivot points near the centre of the chassis, and the stub axle end attached to a double ended
leaf spring. What it means is that the stub axle and control arm (the major part hold your wheels and brakes) is held captive
by the inner pivot point and not your spring. That way if you happen to break your spring on a trip, your axle is not going
to go anywhere. And with the pivot points being at chassis level, this gives you the maximum ground clearance possible.
