Installing Max Air Vents

Hi All,

I'm going to install Max Air Vents on my Lerado 314RE this weekend. I have researched and watched the installation video's, and from what I can see, the vents attach via a bracket directly to the framing of the factory crank up vents.

Nothing I have seen so far speaks to sealing around the vent with any type of self leveling sealant. To me, it appears that while traveling down the road, wind would get under the vent an maybe rip it off or something.

Looking for advice from somebody more experienced with these.

Thanks

They don't fit flush to the roof and the wind doesn't seem to bother them because of the way they are designed. They work well keeping the rain and other misc stuff out.

Sounds good.

Thanks

The mounting is very secure and the vent cover itself is actually pretty robust, much more than the vent lid itself. They recommend to not caulk the MaxxAir vent cover bottom to allow air circulation and avoid condensation.

No worries if you follow the installation instructions (primarily, the opening faces the rear of the trailer).

Make sure when installing the L shaped brackets, make sure they are installed high enough so there is a slight gap between the vent over and the roof membrane. This makes it easier to rinse out crud that builds up between the roof and the vent shroud. (Leaves, bugs, etc). Install is very easy, just take your time when marking and drilling holes in roof vent lip.

Just installed one on my unit last Friday. The frame does mount to the roof, but you need to use butyl tape on the bottom side, and then use some self leveling Dicor on the edges making sure you cover the mounting screw heads.

The one in my bedroom has been there for a few years and no leaks, the rubber gasket that the actual vent seals against is all you need for that seam.

Because of the vent design, no vent cover is required.

I think there's some confusion between air vents and vent covers?

Seems like it.

Vents like Max air have a scoop lid that doesn't require a vent cover.

There are a few different vent covers, including max air and Max air II. These do use brackets that attach to the vent.

Well, if we are talking vent covers over a MaxxAir vent, I made a video about that to.
