A display for a transport unit. The transport unit includes a vehicle, a trailer that defines a space, and a sensor that is in communication with the transport unit and that senses a parameter of the transport unit. The display unit includes a housing that is attachable to the trailer, and a display portion coupled to the housing. The display portion includes a screen configured to display the parameter. A controller is in electrical communication with the display portion to display the parameter on the screen. The controller is programmed to selectively switch the screen between a forward view mode and a mirror view mode such that the parameter is readable on the screen from outside the vehicle and from inside the vehicle based on a relationship between the vehicle and the trailer.
