antenn I spotted a similar van this year, do you know its name?
The trucks are exclusively build for UPS by a number of different manufacturers, depending on the country they are build for. In the USA they are build by Grumman-Olson. German trucks are seemingly often based on a chassis made by Mercedes-Benz and are fitted with a body made by "Kässbohrer" or "Spier Fahrzeugwerk GmbH". There are different model numbers depending on the manufacturer of the chassis that was used, but I am really no expert on this particular subject.
