1998 FORD F SERIES Structure Problems

THIS WAS NOT A PARTICULARLY BAD INCIDENT, BUT IT COULD VERY WELL HAVE BEEN. I CONSIDER IT A 'CLOSE CALL' FROM WHICH THERE IS A WARNING TO BE HEARD. THE STRAPS HOLDING UP THE GAS TANK ON MY F-150 RUSTED THROUGH, DROPPING THE TANK [FORTUNATELY AT LOW SPEED WHERE I COULD STOP FAST - EVEN SO, ANOTHER FOOT OR SO AND I WOULD HAVE BURST THE TANK AGAINST A SEWER GRATING]. THE TANK WAS RUST-FREE, AS WERE THE VERTICAL PARTS OF THE STRAPS. I THINK THAT THE PLASTIC PAD BETWEEN THE STRAPS AND THE TANK HELD WATER AGAINST THE STRAP, RUSTING IT. THE PAD WRAPS AROUND THE STRAP, AND I BELIEVE SCOOPED WATER THROWN BY THE TIRES. I SUGGEST EITHER A PAD REDESIGN TO ELIMINATE THIS, OR THAT THE STRAPS BE OF STAINLESS. THE STRAPS APPEARED TO BE INTACT, BUT THE METAL WAS PRETTY MUCH CONVERTED TO RUST WITHOUT CHANGING...
