Existing comment: Grumman Corporation's Long Life Vehicle, or LLV

Long Life Vehicle:
After the 1950s tests, the next revolution in postal vehicle service came in the 1980s. By then, even the sturdiest jeeps were showing their age. This time, officials decided to have their vehicles made to order. They provided potential contractors with a list of requirements, and challenged each to build the best carrier vehicle from scratch.
Vehicles were tested in Laredo, Texas in what one postal official called "the most grueling test of a government vehicle this side of the M-1 tank." Grumman Corporation's Long Life Vehicle, or LLV, emerged victorious. Now a staple of American neighborhoods, the boxy LLVs began service in 1986. This LLV was the first such vehicle produced for the Postal Service. These right-hand drive vehicles continue to make up the bulk of the postal fleet, as 142,236 LLVs help deliver the mail every day.
