Height adjustable trailers and trucks and methods of operation thereof

A height adjustment apparatus, comprising:

• a power supply;
• a drive wheel;
• a drive motor configured to rotate the drive wheel via power from the power supply;
• and
• a suspension linkage pivotably coupled between the drive motor and at least one of a chassis or a cargo box associated with a transport vehicle;
• wherein the drive motor is configured to modify a position of the suspension linkage, thereby causing an adjustment to a height of at least one of the chassis or the cargo box.

A method, comprising:

• determining, by a control system, to adjust a height of at least one of a chassis or a cargo box associated with a transport vehicle to a desired height;
• determining, by the control system, a desired position of a suspension linkage based on the desired height, the suspension linkage being pivotably coupled between a drive motor and at least one of the chassis or the cargo box;
• and
• instructing, by the control system, movement of a drive wheel by the drive motor, via power from a power supply, to modify a position of the suspension linkage to the desired position, thereby causing adjustment to the height of at least one of the chassis or the cargo box to the desired height.
