Looking Back on the Grumman LLV Mail Truck

"The Grumman LLV, or Long Life Vehicle, has been serving the USPS for many years. Its initial lifespan was set to be 24 years, but by 2009 it was realized that this vehicle could last up to 30 years. A vast majority of LLV mail trucks have been on the road for over 27 years, which is a truly impressive feat."
