It has 12 wheel steering controlled by the HOG at the back. I have "cheated" slightly by making the two front axles steer with the same angle, this was necessary because I wanted to avoid any gear increase between the axles as it would be likely to jerk the steering. There is a dummy V8 engine connected to axles #5&6. The three levers in the front controls four motorized functions in the chassis:
1. Rotation of the invisible superstructure.
2, 3 and 4: Swivel, extract and deployment of the stabilizers.
Most difficult by far was the stabilizers. The goal was to make them fully functional and controlled from the chassis without using seperate motors in each stabilizers. The solution was to mount them on seperate turntables, and use the same technique as in 8043 and 8258. To make the deployment of the stabilizers possible after being extracted I've used the old gray 20 tooth double bevels sliding on a 12L axle as they stick very poorly.
More pics can be seen at Brickshelf as soon as it's approved. A proper presentation and videos will probably come when I finish it.
