Adams/Chassis has three versions of a trailer model, a simple model, and two variations of an advanced model one with load leveling ability and one without. To use the simple model, please look at the truck_trailer.vdb example vehicle database and to use either of the advanced models, please look at the trailer.vdb and trailer_ll.vdb example vehicle databases.
All of the example trailer databases have system files that reference a full vehicle configuration and both the advanced models have half vehicle (rear only) configurations that will exercise just the trailer part of the model.
To add an advanced trailer to your existing model, copy over the appropriate trailer database to your local directory and reference the trailer rear and wheel subsystems in your vehicle configuration file.
