2002 ACCUBUILT VAN Structure Problems

PONTOON BOAT TRAILER, MANUFACTURED BY HAWKEYE LEISURE TRAILERS LIMITED, HUMBOLDT, IA 50548, MODEL # MH20RS, V.I.N. [XXX], MANUFACTURED FEB, 2002. *NM ON SATURDAY OCTOBER 9, 2004 WHILE TRAVELING AT ABOUT 50 MPH ON A RURAL IOWA HIGHWAY NEAR WESLEY, IA THE RIGHT WHEEL FENDER OF THE TRAILER FELL OFF. THERE WERE NO INJURIES OR DAMAGE TO OTHER VEHICLES. THERE WAS A VEHICLE FOLLOWING ME BUT THE FENDER WENT TOWARDS THE DITCH INSTEAD OF REMAINING ON THE HIGHWAY. AFTER RECOVERING AND INSPECTING THE FENDER I FOUND THAT IT HAD ONLY 5 SMALL SPOT WELDS ALL OF WHICH HAD FAILED. SUBSEQUENT INSPECTION OF THE LEFT FENDER SHOWED THE SAME SITUATION WITH 5 SMALL SPOT WELDS OF WHICH 4 HAVE FAILED. HAD THE LEFT FENDER FALLEN OFF THERE IS A VERY HIGH LIKELIHOOD OF VEHICLE DAMAGE AND INJURY. ALTHOUGH THE TRAILER IS 2 YEARS OLD IT HAS BEEN USED VERY LITTLE WITH LESS...
