The Grumman LLV has a payload capacity of 1,000 pounds. That capacity is the vehicle’s rated cargo load, not the truck’s total curb weight or gross vehicle weight.
The LLV was designed specifically for the United States Postal Service, with a right-hand-drive layout that places the carrier close to roadside mailboxes. Its cargo area includes a large metal tray where a passenger seat would normally be, helping organize trays of letter mail and parcels.
The truck’s 1,000-pound capacity was double that of the older Jeep DJ-5 postal vehicle it replaced. The LLV also emphasized maneuverability: its tight turning radius, low gearing, and three-speed transmission suited frequent stops on residential delivery routes.
A common mix-up is confusing the payload figure with the LLV’s engine or chassis specifications. The body was built and assembled by Grumman, while the chassis was derived from General Motors designs related to the Chevrolet S-10 Blazer. The USPS later sought the Next Generation Delivery Vehicle to replace aging LLVs.
