In which Pennsylvania borough was the Grumman LLV assembled?

The Grumman LLV was assembled in Montgomery, Pennsylvania.

Montgomery is a borough in Lycoming County, and it is the locality traditionally associated with the Grumman plant that built the postal trucks. The facility belonged to Grumman’s Allied Division and produced the LLV for the United States Postal Service during the late 1980s and early 1990s.

There is a geographic wrinkle behind the answer. Detailed production descriptions place the factory in Clinton Township, which borders Montgomery, while the plant’s mailing address and the model’s standard assembly listing identify Montgomery. That is why both place names can appear in accounts of the truck’s manufacture. For a quiz asking for the Pennsylvania borough, Montgomery is the canonical answer.

Production was substantial: Grumman won a major USPS contract in 1986, and the factory eventually completed about 95 LLVs per day. More than 100,000 were ultimately purchased, making the Montgomery-area plant closely tied to one of the most recognizable American fleet vehicles of the late twentieth century.
