The Grumman Long Life Vehicle (LLV) is a mail truck model primarily used by the United States Postal Service. The LLV is based on a Chevrolet S-10 pickup truck chassis with a custom aluminum body, and was manufactured by Grumman from 1986 to 1994. Most LLVs were sold to the USPS, although some were purchased by other customers, including Canada Post. The LLV design is optimized for local mail delivery, featuring right hand drive and a small turning radius for easy access to mailboxes.
The LLV was designed for a long service life of 24 years, and the USPS has kept its fleet in service well past its planned lifespan. The USPS had over 130,000 LLVs in service as of 2024, all of which were past their 30 year service life, making up 57% of the local delivery fleet. The USPS LLV fleet is planned to be replaced by multiple types of vehicles, including commercial off-the-shelf trucks and the Oshkosh Next Generation Delivery Vehicle (NGDV). The first NGDVs entered service in 2024.
