As USPS is getting better at delivering packages (even subcontracting to deliver UPS packages to residential customers), they need bigger delivery trucks. The Grumman truck was bigger than the Jeep it replaced. Vehicles always seem to get bigger with each new generation. Communal mail boxes in most new subdivisions now make mail carriers more productive. So, they need to carry more mail when they leave the post office.

Those Oshkosh vans will end up costing about $37k each, way more expensive than the stop-gap Mercedes-Benz Metris and Ram ProMaster vans USPS is now buying. I wonder what one of those windshields cost.
