We recently purchased a new Forest River 5th wheel toyhauler. When the dealer was setting it up and checking out the systems, they noticed that there was a water leak. To find where the leak was coming from they cut several holes in the underbelly before finding that it was coming from the fresh water tank. The leak was fixed, but they did a poor patch job on the several large holes in the underbelly. We want this fixed properly. Can anyone give some good advice on the best way to do this repair, without opening a can of worms? We feel that a different approach should have been used to find the leak, without causing all this damage. Thanks for any help you can give. Harriet
