WHILE VISITING A FAMILY FRIEND CONSUMER DISCOVERED A WATER LEAK T IN HIS CARAVAN. THIS LEAK RESULTED FROM WATER RUNNING DOWN THE EXTERIOR ROOF GROOVES AND DOWN TO THE BACK OF THE VAN. IT HAD A CRACK IN THE WELD THAT WAS FOUND ON BOTH SIDES OF THE UPPER PORTION OF THE VAN BODY, WHERE THE REAR HATCH WAS LOCATED. THE WATER ENTERED THE CRACK AND RAN DOWN THE INSIDE OF THE VAN . ALSO, PUDDLES WERE FOUND UNDERNEATH THE CARPET, WHICH RESULTS IN A MILD WET CARPET, BUT EVEN WORSE, RUST.*AK I LIFTED THE REAR CARPET IN MY VAN AND THERE WAS WATER AND THE CARPET PAD WAS WET. I HADN'T NOTICED IT BEFORE BECAUSE WE HAVE A PLASTIC LINER TRAY IN THE BACK. I BELIEVE MANY PEOPLE HAVE THIS PROBLEM BUT ARE UNAWARE OF IT.
