Massive Chrysler Ram Promaster delivery vans are making their way to postal work units to be used for large package deliveries. The USPS ordered 9,113 of the 2016 Ram ProMaster 2500 cargo vans for an undisclosed price.

The new vans are significantly larger than current postal delivery vehicles. A placard on the dashboard says the clearance height is 8 feet, five inches. The increased height allows carriers to walk into the cargo area standing straight up. There is a built-in retractable jump seat for a passenger or route examiner.

The vehicles are not right-hand-drive and therefore cannot be used for mounted routes. The USPS expects to award a larger contract in 2017 to replace its aging fleet of 180,000 delivery vehicles.
