1. A vehicle trailer comprising: a body defining a storage space;a plurality of wheels connected to the body;a loading dock locking system connected to the body at a rear of the body, the loading dock locking system comprising:a U-shaped member configured to be locked to a loading dock, the U-shaped member having an elongate arm and a perpendicular bar connected to a distal end of the elongate arm, the bar configured to be locked to the loading dock;wherein the U-shaped member is movable between a stowed position for when the trailer is in transport, such that the arm is positioned under or within the body, having the U-shaped member oriented approximately parallel to a floor of the body, and a vertical locking position for locking the trailer to the loading dock, such that the arm is extended from the body and is oriented approximately vertically downward away from the body. 2. The vehicle trailer of claim 1 further comprising a safety braking system in communication with at least one of the plurality of wheels of the trailer, and wherein the safety braking system is configured to activate automatically if the U-shaped member is not in the stowed position, an activation of the safety braking system causing at least one of the plurality of wheels to stop a rotation. 3. The vehicle trailer of claim 2 further comprising a switch in communication with the safety braking system, the switch being positioned to be physically actuated when the U-shaped member is in the stowed position, the actuation of the switch preventing activation of the safety braking system. 4. The vehicle trailer of claim 1 wherein the U-shaped member is slideable from the stowed position to an extended horizontal position, and only when in the extended horizontal position is hingedly movable from the extended horizontal position to the vertical locking position about an axis at a proximal end of the arm. 5. The vehicle trailer of claim 1 wherein the U-shaped member is positioned below the floor of the body when in the stowed position. 6. The vehicle trailer of claim 1 wherein the arm defines a stowed position aperture at a distal end of the arm, and defines a vertical locking position aperture at a proximal end of the arm; and further comprising a spring loaded pin configured to fit into each aperture, the spring loaded pin having a spring biasing it into the apertures and being movable away from the apertures such that when moved away, the U-shaped member may move between the stowed and vertical locking positions and when the spring loaded pin passes through the apertures, the U-shaped member is prevented from movement. 7. The vehicle trailer of claim 1 wherein the U-shaped member has two arms, each arm joined together by the bar at the distal end of each arm. 8. The vehicle trailer of claim 1 further comprising a gusset plate attached to a floor of the body, the arm connectable to the gusset plate when in the vertical locking position. 9. The vehicle trailer of claim 1 wherein the arm is slideable within a channel formed by a tube when moving to and from the stowed position. 10. The vehicle trailer of claim 1 further comprising a bumper. 11. The vehicle trailer-of claim 1 further comprising an electronic sensor, the sensor being positioned to be actuated when the U-shaped member is in the stowed position. 12. The vehicle trailer of claim 1 further comprising a lift gate. 13. A vehicle comprising: a body defining a storage space;a plurality of wheels connected to the body;a loading dock locking system connected to the body at a rear of the body, the loading dock locking system comprising:a U-shaped member configured to be locked to a loading dock, the U-shaped member having an elongate arm and a perpendicular bar connected to a distal end of the elongate arm, the bar configured to be locked to the loading dock;wherein the U-shaped member is movable between a stowed position for when the trailer is in transport, such that the arm is positioned under or within the body, having the U-shaped member oriented approximately parallel to a floor of the body, and a vertical locking position for locking the trailer to the loading dock, such that the arm is extended from the body and is oriented approximately vertically downward away from the body; andwherein the U-shaped member is slideable from the stowed position to an extended horizontal position, and only when in the extended horizontal position is hingedly movable from the extended horizontal position to the vertical locking position about an axis at a proximal end of the arm. 14. The vehicle of claim 13 further comprising an electronic sensor, the sensor being positioned to be actuated when the U-shaped member is in the stowed position. 15. The vehicle of claim 13 wherein each arm is slideable within a channel formed by a tube when moving to and from the stowed position. 16. The vehicle of claim 13 a safety braking system in communication with at least one of the plurality of wheels of the trailer, and wherein the safety braking system is configured to activate automatically if the U-shaped member is not in the stowed position. 17. The vehicle of claim 13 further comprising a lift gate.
