Owner report 10579727 · 2014-04-14 (April 14, 2014)
WHILE DRIVING MY NEW 2014 KEYSTONE, CARBON 5TH WHEEL ON THE FREEWAY, THE SCREWS THAT HOLD THE OUT DOOR COMPARTMENT FOR THE FUEL TANK HOSE FELL OUT AND THE DOOR WAS HANGING ON BY ONLY SEVERAL SCREWS. IF THE DOOR HAD FALLEN OFF OR COME OPEN AND THE FUEL NOZZLE FELL OUT IT COULD HAVE CAUSED A MAJOR ACCIDENT ON THE FREEWAY. THE RV DEALER ALSO REPLACED THE SCREWS THAT FELL OUT THAT HOLD THE WHEEL COVER AREA ON THE SLIDER FROM FLAPPING IN THE WIND. IN ADDITION THE BRACKET WAS ALSO CRACKED IN HALF. MAJOR POOR DESIGN. *JS
