Claim 13:
14. A method for dynamic tow of a trailer comprising:
during a first time period:
detecting a direction of motion of the trailer;
detecting a first force applied to a kingpin arranged on a proximal end of the trailer, by a hitch of a tow vehicle;
detecting a first incline angle of the trailer;
calculating a first target preload force opposite the direction of motion and inversely proportional to the first incline angle; and
in response to the first force falling below the first target preload force, triggering a motor, arranged in a drive system located proximal a distal end of the trailer, to increase torque output in the direction of motion to decrease a first difference between the first force and the first target preload force; and

during a second time period:
detecting a second force applied to the kingpin by the hitch of the tow vehicle;
detecting a decline angle of the trailer;
calculating a second target preload force opposite the direction of motion of the tow vehicle and inversely proportional to the decline angle; and
in response to the second force falling below the second target preload force, triggering the motor to increase torque output opposite the direction of motion to decrease the second difference between the second force and the second target preload force.
