Create: Tow & Haul

Towing gear runs through real physics rope rather than a teleport or a fake pull. A redstone-controlled winch reels steel rope in and out, a tow bar acts as the anchor point on each vehicle, and a rigid drawbar carries Create shaft rotation between two tow bars joined by a coupling. Anything a player wants to drag can be attached to a tow bar, and the rope stays a constraint between two sub-levels.

The hitch is built to behave like a real towing hitch. The joint locks only three linear axes, so rotation stays free, and a trailer swings with the towing vehicle through corners rather than being locked to its heading. Both vehicles keep their wheels on the ground over hills, slopes and bumps. The coupling rolls through a full 360 degrees of cornering, and a slope will not flip the rig. Shears cut the rope and return a Steel Rope item, and breaking either end block drops the link. A Create wrench uncouples a hitch and also rotates the winch and the tow bar.
