Trailer-mounted mock landing gear

A method for calibrating a force sensor and a torque sensor of a tow vehicle, the method comprising:

• engaging a holding device of the tow vehicle with at least one replicated element of a towed vehicle, wherein the at least one replicated element is coupled to a shaft having a first end rotatably coupled to a frame that is attached to an underplate of a lowboy trailer and a second end configured to couple to the at least one replicated element;
• applying a predefined longitudinal force to a torque-neutral point on the shaft such that the predefined longitudinal force is applied to the shaft without applying a torque thereto;
• determining, by a computing device, a reading of the force sensor of the tow vehicle;
• applying a predefined torque on the shaft;
• determining, by the computing device, a reading of the torque sensor of the tow vehicle;
• and
• calibrating, by the computing device, (i) the force sensor based on a comparison of the reading of the force sensor and the predefined longitudinal force, and (ii) the torque sensor based on a comparison of the reading of the torque sensor and the predefined torque.
