The Bushtracker suspension is a fully tandem independent and load-sharing suspension. The fact that
the load-sharing characteristic reduces the shock of rough tracks to the payload is why the Defence
Department likes it so much.

The load-sharing characteristics are so important, because when the leading arm of the suspension
hits an obstacle it shifts half of the load onto the rear arm of the suspension, and when the rear arm of
the suspension hits the obstacle  it shifts half of the load onto the front arm of the suspension. The net
effect is that the suspension articulates rather than delivering the shock of the road to the van twice in
the tandem form. It is the suspension that moves in the ruts, shifting the load front to back and then
back to front, rather than jarring the van by delivering the entire shock to the van with each wheel. It is
simply the best. It has been around for about 20 years, but is not widely used as it is more expensive
than normal caravan suspensions.

You must have a fully independent suspension for several reasons. Here's a couple: One, the independent leaves a tunnel through the centre of the van for higher ground clearance, an axle suspension drags the axle when the wheels fall into the rut, and the axle acts like a boat anchor to bog the tow vehicle. Two, and most importantly, the independent breaks up what is called in engineering language "harmonic motion" which basically means that when there is just the right speed and timing on the ruts, the bounce builds on itself to create a destructive force. When you see it you will like it and most importantly it is load sharing in a tandem mode.

Bigger brakes & bearings

We have also done the engineering to incorporate the option of 12" two piece hub drum commercial brakes into our suspension and that is a major improvement over the standard 10" or 12" caravan brakes. Besides better brakes, our larger hubs allow for bigger bearings as well. Our suspension can be fully aligned, as each A-frame is adjustable. It is simply the best, and stands head and shoulders above the rest.

What we are about is building the best and strongest, not just "the look". As it turns out, when you compare apples and apples (as close as you can get since we offer things not available anywhere else), if you were to price up their vans with what we offer, we are also very comparable in price.
