Truck & Trailer rigging on constrained path

I'm attempting to rig a semi-truck and trailer to a constrained path.
I experimented with the following instructions:
[QUOTE] I was just figuring how a normale trailer would work (and define its position/rotation). so what you need, is a dummy at the center of your middle axle of your trailers wheels (depending on how many axles, it's either the midle axle [uneven number of axles] or its between the axles [even number of axles]. call this AxlePivotDummy or something like that.
Then you need a dummy at the pin of your trailer where it is hooked up to your truck (which defines where its going and everything). call this one PinDummy (or propably somethimg more meaningfull.).
You link the PinDummy with your Truck (so it moves with the truck). Then you add a look at constraint from your AxlePivotDummy to the PinDummy. That drives your rotation of the Trailer.
And now you need some sort of PositionConstraint for the Truck that is driven by the PinDummy. Not sure how exactly that could work, but maybe you'll figure that one out ;)
sorry, that it's just half an answer, but maybe it'll point you in the right direction (or anyone else :D)
