Was lovely to catch up with you both at Swindon. Looking forward to the 21st Sept!

I drive a truck with a trailer with a rear steer axle. We have 2 types. One works on a castor type system, but the one that relates to the trailer you are trying to build, the trailer steering works on a wedge in the fifth wheel. The pin on the trailer is on a turntable that uses the wedge to lock and locate with the trailer. When you turn, the turntable turns which in turn, through cables, turns the rear axle. Then a clutch system stops them turning beyond 40 degrees so the trailer can still be spun on the spot, dragging the axles. With multiple axles like you have, the axle turn ratios will step as you move back. The front axle will barely turn, but the rearmost will turn a lot. I'm not sure of the geometry, but I know if you look for Lego building plans online, someone would have done it in Lego. Might be a good starting point for a design of the trailer steering.
