I haven't tried this myself, but someone reported noise from the mirror arm was a problem, and overcame this using AirTabs.

You can try pulling the mirror in and see if the noise is less and that would be a strong indicator that this is indeed the problem.

If so, see http://www.airtab.com/en/Product_Applications_24/29.html. Look to the bottom of the page for the text above this picture:



I suspect that the wind problem for Class C's is not the the same, though, so this solution might not work.

A Class-C or Super-C with the common cab-over bed, creates a real good wind "funnel". It forces 2 to 4 times the volume of air around to the sides of the cab that would otherwise pass above the vehicle. Thus, you get a lot of wind noise. You actually simulate what the wind noise would be if you had simple van or truck, traveling down the highway at 2 to 4 times your actual speed.

You have shared different solutions to combat it. I hope they work for you. But there is only so much you can expect.

The aero-dynamic cap approach we like to call a B+, allows all frontal air to continue it's natural path up and away from the windshiled, thus greatly reducing the wind noise on the sides by the cab doors.

I owned a very small and aero-dynamic class-C Seen Here for many years. At 55-60mph, with the window rolled down, when you put your hand out the window to feel the air coming across the windshield, it was "EXTREME". It felt like we were traveling 125mph. With my new B+, it is normal as would be expected, traveling in a car.

A short lecture on aero-dynamics and wind noise. I hope I didn't bore you.
