1997 Oakwood trailer, under the floor their is a bladder, it is full of water. There is no water pipe there. Can this water be coming from the sides of the trailer from when it rains?? You can see that the rain runs down almost in the same spots from were the gutters let the water run out.Could this be my problem??
