Abstract: A door mounting system for mounting a door includes a door mounting frame and a lifter mount. The door mounting frame is attachable to a door and is removable from that door. The lifter mount is attachable to a propulsion device such as a forklift. The lifter mount is attached to the door mounting frame so that the propulsion device provides a way to transport the door mounting frame and the door to a location where it is desired to install the door.

Abstract: A system is disclosed for testing electrical devices on a trailer without a truck being connected to the trailer. The system includes a control cable and a test control box. When an operator activates the test system, the box selectively powers a number of different electrical devices on the trailer through the control cable. As the different devices are powered up, the operator is able to physically inspect the trailer to be sure that each device works or does not work. The system may include one or more closed circuit cameras and a display screen operatively engaged therewith. Each camera is positioned to capture an image of one of the electrical devices and to transmit that image to the display screen where it is viewable by the operator. The cameras and screen allow the operator to remain in a single location while testing all of the devices on the trailer.
