Been driving the LLV (Long Life Vehicle) for 17 years now. As a matter of fact, my vehicle had a breakdown today (naturally on our first 100+ degree day of the year). Although the USPS's financial problems have been covered quite a bit in the news lately, the condition of those tires is NOT a result of poor maintenence or the budget crunch. The issue is a lazy carrier not turning in a repair ticket for those obviously unsafe tires. We are required to perform a vehicle check every morning, including checking the tires, all lights and signals, and checking for leaking fluids. Most of these LLV's are over 25 years old and still performing their jobs, although age is taking it's toll. The body's are pretty much indestructible. They were made by Allied Grumman (the defense contractor) and are all aluminum. The drive train and frames are by Chevrolet, basically an S-10 pickup truck with a 4 cylinder Vortec engine with the A/G bodies bolted on top. Word from the maintenence people here in Phoenix is that the Post Office is looking to convert them into all electric vehicles. They are reportedly testing a few eLLV's somewhere along the east coast.
