I have a new C Class moho with a vent above the overhead bed that creates a lot of wind noise while driving at highway speeds.Any ideas how to minimize the wind noise? Has anyone used window/door insulation strips, or other products to minimize the wind noise? A friend recommended adding a roof vent cover, but I'd like to try other remedies before resorting to adding the roof vent cover.Thanks in advance for any helpful suggestions.

If this is the standard 14" vent then they make pillows that fit in the opening for insulation purposes. If it's one of the bigger escape hatches I would think you could just get a piece of thick foam rubber to do the same thing.

Check to see if the vent seal Like This is in place,it fits over the rim of the metal vent.If it is left out or misshapen or worn out the vent cover will not seal properly when closed.Vent covers are an excellent idea,they will protect your vent lids and prolong their life,and with our year round good weather you can keep them open without the fear of rain getting in. Oh what am thinking we never get rain :B

Install a MaxxAir type cover over it.

Are you saying that the vent is closed but not sealing?If the vent is open, the only option is a cover.

I checked the rubber seal around the metal flange and it's in good shape. The entire vent assembly is in good shape. I think the vent cover doesn't sit snug enough against the thin rubber seal and lets air get through.I'm going to see if the hardware store sells thin, self-adhesive weather stripping that I can stick to the vent cover flange to lessen the gap between the side of the rubber seal and the vent cover.
