The Rampmaster 17.5K is parked between the R-12 hydrant-servicing vehicle and the R-11 fuels truck April 14, 2010 at Joint Base McGuire-Dix-Lakehurst, N.J. The large capacity refueling vehicle has a fuel capacity of 17,500 gallons, which is almost equivalent to three R-11s. JB McGuire was chosen by the Air Force Petroleum Office and Air Mobility Command to be the first and only installation to test the vehicle. (U.S. Air Force photo/Wayne Russell)
