We were in the UP for a week and spent 3 days at one campground then moved to another for 4 more days. Each of those campgrounds has about 50-75 sites, so a variety of trailers, tents and motorhomes. Of the trailers with FILON front caps, I'd say about half of what I saw had some degree of "oil-canning" at the top of the front cap. Keep in mind, this is northern Michigan, usually no hotter than about 85F and being "close to Lake Superior/Michigan" usually very humid. The brands ranged from Keystone to almost all of the competition, so there wasn't any "one brand is worse than the rest", at least in this very limited comparison.

It seems to me that there are three types of trailers, those that have FILON front caps, those with fiberglass front caps and those with aluminum/other type front caps (Airstream, etc). Typically, as the "front cap material improves", so does the price range... I won't go so far as to say, "You get what you pay for", I would suggest that as the price increases, so does the quality of the construction materials used.

That said, it's better to have a FILON capped trailer and go camping than it is to not be able to afford a trailer and sit home..... So, there is a "place in this world" for less expensive trailers that fit into the financial ability of growing families or those on a budget.

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.

You'd think the front would be the most important part as that is the place that is taking all the wind, debris when traveling. Mine has the aluminum on the bottom half, so why skimp at the top???
