Maneuverable ergonomic trailer stands are disclosed. An example portable trailer stand includes: an elongate upper ledge, a post coupled to the upper ledge, an extendible leg telescopically coupled to the post, the upper ledge being vertically movable to selectively engage and disengage an underside of a trailer based on movement of the extendible leg relative to the post, and a plurality of wheels coupled to the post, the post to maintain the plurality of wheels at a substantially fixed distance from the upper ledge as the upper ledge is vertically moved, each of the plurality of wheels to be equidistant from a vertical axis traversing through a center of the upper ledge.

A method for manufacturing a linear jack includes disposing a first rotating screw at least partially within a coarse nut, wherein the first rotating screw is threadedly coupled to the coarse nut. A second rotating screw is disposed at least partially within a second sleeve, wherein the second rotating screw is threadedly coupled to the second sleeve. The first rotating screw is disposed at least partially within the second rotating screw, wherein the first rotating screw is slidingly coupled to the second rotating screw via a splined connection. The second sleeve is disposed at least partially within a first sleeve, wherein the second sleeve is configured to translate with respect to the first sleeve.

A lift for a hitch mounted cargo carrier has a linear actuator having fixed and moveable portion. A drive extends and retracts the moveable portion relative to the fixed portion along an axis of the linear actuator. A hitch mount is secured relative to the fixed portion that is sized to be received by a hitch receiver of a vehicle such that the axis is vertically oriented and the moveable portion extends from a bottom end of the fixed portion. A moveable hitch receiver is secured to a bottom end of the moveable portion, the moveable hitch receiver being positioned such that the receiver traverses the axis. The hitch mount and the moveable hitch receiver extend substantially perpendicularly to the axis and the hitch mount extends substantially anti-parallel to the moveable hitch receiver and on an opposite side of the linear actuator.
