G`day Warnie,
I may be able to help. I had a Little Robin custom built by Driftaway in
Geelong about 5 yrs ago, though the original designer had long retired. Nevertheless the new bloke did a great job of it. Anyway I chose the Alko ( rubber axle
suspension ) I can`t remember the correct name for it, but the main reason for choosing it was because of my carport height was pretty average and this
suspension offered the best performance for my required static height. A bonus is the ease of attachment and it really is a fantastic idea the way it works. I don`t own the van or the house anymore so can`t provide pics. I only used it on formed roads so I can`t fib and say I went track driving, but that was in the plans to do when it was built and can`t think of a reason you couldn`t use it on tracks. Look up Alko suspensions and you`ll find the info you need, that`s what I did at the time.
Cheers Rog

If you are going to use an axle with leaf springs I would use Landcruiser front springs. They are long enough to give a supple ride and will also allow a fair bit of travel. The ability to soak up road bumps with a longer travel supple
suspension which doesn't shock your van, and break the eggs, is of great benefit.
I did exactly this to my 6x4 trailer for outback use and it works perfectly. I also added shock absorbers to control the moving mass of trailer and the wheels and axle. It doesn't bounce at all.
If going off road, the Alko rubber stuff doesn't have long travel, and it shakes the hell out of everything as the arm flaps up and down oscillating on the rubber. Ok for horse floats but not offroad IMHO. If used carry a spare for each side.
The choice of tyre size for using the tyre as the first
suspension medium is also worth consideration. The biggest distance between the road and the rim ie highest profile you can reasonably use, is good to have.
Cheers
