Have you ever wondered how your RV was constructed? In this video, I show you what is behind your RV’s J-metal (sometimes called J-wrap). Knowing more about how your RV is constructed can help you maintain it and perform a few extra steps to help prevent damage in the future!
This can be a very dangerous situation for those traveling behind you in high winds. There has been a lot of talk about this on the National Highway Traffic Safety Administration website over the years.
You will notice that a lot of manufacturers have started adding screws to secure the top of the J-metal through the S or Z locking molding. If your unit doesn’t have these screws or have an insufficient amount of screws, I would recommend that you take the time to secure your RV’s J-metal.

And once water gets in… Most of our kitchen is a slide room. Keystone added a foil layer under the RV refrigerators (we have a dual set) to protect the slide floor from leaks and/or condensation. Nice – except water got between that foil and wrapped floor. The foil prevented any evaporation and yep, the manufactured wood floor disintegrated. $7K floor replacement, most of that labor for the kitchen and trim removal and replacement.
Jim,
Thank you for sharing, I completely understand and am very sorry this happened to you. That’s one of the reasons we always talking about going back over and resealing what the manufactures didn’t seal and in most cases sealing it better.
Seemed like a good idea to “some factory engineer” in the factory, but I would rather have a “guy” with real world experience thinking up a “better” idea.
Thank you, Justin.
