A work vehicle includes a vehicle body frame supported on a ground surface via a wheel unit and a pair of left and right fenders that can be reversed from a normal posture to a reversed posture via a reversal mechanism, an inside area covered by the fender under its normal posture becoming exposed in the reversed posture of the fender. The fender is maintained under the normal posture and the reversed posture. A first accommodating profile is formed in the surface of the fender, the first accommodating profile being capable of accommodating an article when the fender assumes the normal posture.

A motor vehicle includes apparatus for towing a trailer with a retractable drop leg. A backup camera captures a detection image with a field of view including the trailer. A vehicle controller detects an initiation of driving with the trailer being connected. A pattern memory prestores at least one image pattern indicative of an extended position or a retracted position of the drop leg. An image scanner receives the detection image when the initiation of driving is detected, wherein the image scanner compares the detection image and the at least one image pattern to detect whether the drop leg is in the extended position. A notification device responsive to the image scanner alerts a driver if the extended position is detected.

Power dollies can be used for moving moveable objects such as trailers. A power dolly could include a frame, a mount and a plurality of wheel sets. The mount could couple the power dolly to a moveable object. One or more of the plurality of wheels sets could be powered. The plurality of wheels sets could be separated into a primary wheel set and one or more support wheel sets. The wheels of the primary wheel set could extend farther from the frame that the wheels of the support wheel sets.
