This is what I received from my dealer.
I did call Jayco in regards to the vent. You had mentioned about putting in a Max Air vent. I spoke to the technician and Jayco, the vent is working as designed. If the vent is left open when it is raining out, water will splash into the vent causing water to get in, as other vents would too.
If you still would like a Max Air vent installed, that would be something Jayco will not cover, as there is no defect with the current vent.
My Response was this.
OK, so that is a pretty bad design when you cant even install a vent cover to prevent water leaking into it. I will have to install a vent myself. The other vent in the bedroom is designed to allow for a vent cover, where this one is not, so I am pretty much forced into replacing this myself. Maybe you can call jayco and explain that to them, and maybe they will absorb the labor of a maxxair and I can pay the cost of the vent
