My 4104 noise is so bad driving into a strong wind that I wear ear plugs but I always thought it was the windows?  Never suspected the mirrors.

They are so neat looking that I have to remove them though.

If there are any holes in any of the mountings, that can result in a loud whistling noise. Sharp edges are another source

If you mount an antenna on them the noise will stop/change the airflow.  Wink

keep in mind that most of your wind noise is generated by the frontal area of the bus and the fact that my your tows there is nothing but sheet metal one layer thick.....

put your ear to a beer can side and have someone blow across the top.

how to make it go away....insulate all the frontal panels

Must be the added round mirrors. We had the OEM mirrors (without the added round mirrors)n our MC-8. We recently removed them and replaced them with a pair of electric heated Ramco mirrors (also without added round mirrors). We have noticed no difference in wind noise.  Jack
