Methods, apparatus, and systems are provided for tracking freight. Embodiments include a tracking device for a trailer containing a load. The tracking device includes a support member, a connector, a housing and a GPS tracker configured to track the location of the load. The connector securely attaches to a container on the trailer and attaches to a seal such that the container cannot be opened without breaking the seal. The support member stabilizes the housing and protects the tracking device during transit of the load. A tracking system may implement to monitor, gather information and report on the tracking device and the load.
