The first vehicle was completed in April 1986. At peak production, 95 LLVs were completed each day, at a rate of approximately one every five minutes.<ref name=UPI-87/> Grumman invested $28&nbsp;million into the factory, doubling its size to {{cvt|213000|ft2}} and increasing the workforce from 250 to 600.<ref name=UPI-87/>

The USPS purchased more than 100,000 of these vehicles, the last one in 1994.<ref name="afvs">{{cite web |url=http://www.afdc.energy.gov/afdc/pdfs/usps_cs.pdf |title=Nation's Largest Alternative-Fuel Fleet Delivers the Goods for the U.S. Postal Service |author=Argonne National Laboratory |author-link=Argonne National Laboratory |publisher=[[U.S. Department of Energy]] |access-date=January 8, 2014}}</ref> As its name suggests, the Grumman LLV is easily capable of a long life. The required lifespan specified by the U.S. Postal Service was 24 years, but in 2009, this was extended to 30 years. The Grumman LLV can easily last over 200,000 miles on its original engine and transmission before needing an overhaul.<ref>{{cite web|url=https://www.motorbiscuit.com/exactly-how-many-miles-usps-mail-truck-last|title=Exactly How Many Miles Does a USPS Mail Truck Last?|work=MotorBiscuit|date=2023-02-14|access-date=2023-02-17}}</ref><ref>{{cite web|url=https://about.usps.com/postal-bulletin/2007/html/pb22207/news.2.4.html|title=Going the distance: This LLV puts long into life|work=[[United States Postal Service]]|date=2007-05-24|access-date=2023-02-17}}</ref>
