What is under my RV’s J-metal?

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 RV 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.
