Me being an x truck driver looking at it,it looks the same set up as a super dog trailer, turntable at the front and a turning point at the tow bar,looking at the photo it would not have a great deal of weight on the tow ball all the weight would be on the tandem wheels and the front dolly, it would be only the weight of the draw bar on the tow ball I stand to be corrected.
PS it is what they call a super dog set up, just two axles is a dog trailer, four axles is a quad dog,three axles at the rear and three axles at the dolly is a TRI. TRI dog trailer I think.

I reminds me of a car trailer I used to use that had a wheel at each corner with the front wheels steering with the drawbar.
I am not sure if it is a turntable. or wheels on fixed pivots steering, but I suspect it would need some form of steering damping to stop it building up and amplifying an oscillation.
I have seen this rig in Caravan work magazine a few times over the past 20 years or so. Various tow tugs include an 70's Range Rover which matched the current wheels and rims, then a series 2 Landrover Discovery. The owner reported it towed very well but reversing was an interesting experience until you got used to it.
