[Knightly] Logging Trailer Version 1

This is a living van trailer to compliment our traction engine, showmans engine or steam roller.

If you have one of the versions of the engine without a tow hitch you can upgrade for free by getting a redelivery.

Once you have the updated version you can click on the tow hitch to link the trailer to the engine. The scripts will allow the full linkset to be driven without the traditional sim-crossing issues of follower scripts. Both the drawbar and trailer itself are articulated and the script calculates the various angles of these and adjusts to suit.

The scripts also allow unlinking so you can drive your van to a destination, unhook and continue driving.
