First FILON that's on the side of your trailer. is several layers of different material sandwiched together to form a wall. What's on the front is a single sheet of material glued to the frame square tubing across the front. Behind it is fiberglass bat insulation. That's why it distorts so easily. It doesn't mean water is leaking in. Construction adhesive doesn't hold forever. After 10-15 years in the sun and heat and cold it breaks down. The stuff on the side lasts longer because it has a much broader contact surface and is not as directly exposed to the elements.
Secondly I think the manufactures stopped using this construction about 10 years ago. You only find it on older trailers.
