- Purpose Built – Rented or owned vehicles can be designed, modified or built specifically to carry a particular product, such as cold chain items, which might require special handling.
- Self Manged Managed Drivers – Organizations in total control over their vehicles will be able to train and supply their own drivers, which will allow for development, specialization and quality control in case of performance issues.
- Customization – Rented or owned vehicle can be outfitted with logos and visibility, and can have customs communications equipment installed and configured.
- Quality control – Using a self-managed vehicle it’s much easier to ensure that the vehicle is used in an appropriate and ethical manner befitting of the agency.
- Time and Complexity - Self-management of vehicles and fleets can occupy a great deal of time, and require excessive attention from management.
- Special Knowledge – Maintaining one or more shipping vehicles requires special skills and knowledge. Unless outside arrangements are made with third party repair services, organizations will have to identify and contract mechanics, and mange manage their own supply chain of spare parts. Dispatch and fleet management is also its own special skill, and requires knowledgeable and trained staff for coordinating movement of multiple vehicles.
- Costs – the start up and investment capital required to obtain vehicles, drivers and parts can be substantial, and aid agencies limited to grant funding may not be able to cover costs all at once. Operating in many contexts will also incur substantial insurance costs as well.
- Single Point of Failure – Organizations that own or manage their own vehicles run the risk of mechanical issues or an accident completely halting use of that vehicle at any time.
- Porters should not carry cargo of excessive bulkiness or weight.
- If the loading point does not have a drive up loading bay, porters should be able to safely step up and down from the vehicle bed without jumping or climbing.
- Porters should only be expected to load for reasonable amounts of time, with breaks in between. Ideally loading teams would be split; 2-4 loaders on the truck and the necessary number of loaders carrying goods to and from the warehouse/depot/discharge point, reducing the need to enter or exit the vehicle.
- Porters should be monitored for unsafe behavour behavior or possible security concerns.
