2013 Keystone Passport, With customer demand for lightweight fuel efficient travel trailers at an all time high, the Passport from Keystone is sure to be the pick of families who want to maximize fuel efficiency, but still maintain all the conveniences of a well appointed, feature packed RV. Passport identified the four most important priorities for our customers: floor plan, weight, eye appeal and price; then designed the Passport to be the perfect combination of all four. Creative engineering has enabled Passport to include high-end amenities without adding pointless weight. Its sleek aerodynamic front-end design and enclosed underbelly reduces wind resistance and increases fuel efficiency. In addition, the Load Equalization, spread-axle system assists in lowering hitch weight and makes towing easier. TraderOnline Ref# 114412525
