non-vehicle request - realistic 5th wheel attachements

[Aperion]

Soo it's always driven me up a wall that trails are able to move about so freely when attached to a truck. I could be wrong but I do not believe trailers are allowed to twist relative to the the truck when attached, so my request is two pronged, and applies only to 5th wheel trailers and trucks
1) make the submesh area around the hook point contactable for all trailers
2) make the 5th wheel attachment point on the truck prevent side to side rotation of the trailer relative to the truck. This would be done by making 4 contacter nodes surround the hook point and these points would rest against the bottom side of the trailer.

I think this would be

I have trouble locating the pin when coupling up so guide rails would be useful.

ok, I just tried this out on the across and it's simpler and easier than I thought, and works very very well.

ok it's simple add two noes 0.3m +- in the z direction from the hook (, h) node with the same x and 7

then connect those two nodes to all the same nodes the hook node is attached to, then hook them to each other and then to the hook node.

and the nodes to the contactor list and your done! here is the added code needed for the actros.
new nodes, add the end of the node list:

; new 5th wheel
79, 4.80, 0.85, 0.95
80, 4.80, 0.85, 1.55

extra beams:

79,18,i
79,19
79,20,i
79,21
79,22,i
79,23
79,24,i
79,25

80,18,i
80,19
80,20,i
80,21
80,22,i
80,23
80,24,i
80,25


79, 80, i
79, 34
34, 80

and nodes 79 and 80 to the contacters list. the Green semi trailer (37tons) is already set up properly, so hook up the actros to and have fun! It's atually much more stable and you won't have trailers tipping on their side when you go around a corner.
