The U.S. Postal Service is currently looking for a replacement for the venerable Grumman LLV delivery truck. We've seen two possible replacements, one from Karsan, and another from OshKosh. There are four other companies that have prototypes under consideration, too, including AM General, Utilimaster, Mahindra, and VT Hackney. Now the prototype from VT Hackney has finally been spied, and it looks pretty interesting.
