The defect
ON CERTAIN FIFTH WHEEL TRAILERS EQUIPPED WITH BEDROOM SLIDE OUT ROOMS, THE FRONT CROSS-MEMBER CONNECTED TO THE HITCH PIN BOX MAY NOT BE OF ADEQUATE STRENGTH.
The risk
IF OVERLOADED, EXTENSIVE USE, ADDED HITCH WEIGHT, AND/OR ROAD UNEVENNESS, STRESS ON THE C-CHANNEL COULD CAUSE THE HITCH PIN BOX TO HAVE CROWNING OR STRESS FRACTURES CAUSING THE UPPER FRAME TO DROP DOWN MORE THAN ONE INCH WHEN CONNECTED TO THE TOW VEHICLE. THIS COULD AFFECT THE STEERING CAPABILITY OF THE TOWING VEHICLE INCREASING THE RISK OF A CRASH.
