A landing gear assembly includes a leg assembly, a gear assembly configured to telescopingly move a second leg portion with respect to a first leg portion, and a drive assembly including a gear arrangement configured to drive the drive shaft of the gear assembly at a high speed and low torque configuration and at a low speed and high torque configuration, an electric motor configured to drive the gear arrangement, and a controller configured to switch the gear arrangement from the high speed and low torque configuration to the low speed and high torque configuration in response to an increase in current draw by the electric motor as the second leg portion moves from a retracted to an extended position, and configured to maintain the gear arrangement in the high speed and low torque configuration as the second portion moves from the extended position toward the retracted position.

A parked freight trailer stabilizer and restraint comprising: (a) a kingpin receiver configured to lock onto a kingpin of a parked freight trailer; (b) a jack operatively coupled to the kingpin receiver, the jack repositionable between a retracted position and an extended position; (c) a tail hold operatively coupled to the kingpin receiver, the tail hold repositionable between a stowed position and a restraining position, the tail hold configured to engage a ground mount; and, (d) a transport receiver configured to engage a transport vehicle.
