2017 FOREST RIVER FR3 Unknown Or Other Problems

SEVERAL TIMES WHILE DRIVING AT LOW SPEEDS UNDER 30MPH, OVER BUMPY ROAD CONDITIONS (MOST RECENTLY A RAILROAD CROSSING) THE FRONT END BEGINS TO VIBRATE, SHAKE AND BOUNCE VIOLENTLY INCREASING IN INTENSITY UNTIL STOPPED COMPLETELY. THIS HAS HAPPENED AT LEAST 9 TIMES IN NON-TRAFFIC SITUATIONS. THE 10TH TIME, WHILE TRAVELING IN SINGLE LANE TWO-WAY TRAFFIC I WAS FORCED INTO A TREE LINED EMBANKMENT BEFORE BEING ABLE TO STOP AND AVOID A REAR-END COLLISION. AGAIN I WAS THEN ABLE TO DRIVE AWAY NORMALLY BUT SUSTAINED DAMAGE AND DESTRUCTION TO PARTS OF MY VEHICLE. I HAVE CONTACTED THE RV MANUFACTURER WHO SAID THIS IS A FORD PROBLEM. THIS LAST TIME I WAS COMPELLED TO ELEVATE THIS SINCE IT COULD EASILY HAVE BEEN A LIFE THREATENING SITUATION. SO FAR I HAVE NOT HAD THIS HAPPEN IN HIGH SPEED SITUATIONS.
