I thought you were not suppose to adjust the side door, but you can add thicker foam striping to stop or slow any air leaks. Also make sure all coach windows are closed and locked. You may all be ahead of me, buy more will follow on this thread.

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.


This could work and I will check it out. The wind tabs are what we call vortex generators. They create vortesies that make the air break up rather than having a smooth slide creating wind noise.

Why not? If it needs adjustment do it. There is no foam in my doors. Adding a thicker piece of rubber may help. Adjusting the door is easier and cost less if you have the tools.

I did mine and it did reduce the wind noise.

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.

This may have all ready been suggested, but have someone else drive, and you climb around in the back and listen for the air noise. Then you will know where to put your energy and time in trying to stop it.

We had bad wind noise on our Forrest River Lexington. We went through the usual taping off the stove vent,entry door, sliding windows and such. We finally tracked it down to the front awning post at the top where the wind accelerates around the cap made a perfect whistle. We experimented with duct tape to narrow it down to the top 1 foot of the channel being the culprit. We removed the tape and cut a piece of foam pipe insulation to fit and forced it in the channel and no more noise.

I know this may be something you already considered but if you have your backup camera and monitor on there is a remote mic and you can adjust the volume on that. Some people leave that on when they are driving and forget to turn the volume down. Just a thought!

Has anyone tried these door visor/wind deflectors? They are relatively inexpensive. I had them on one of the pick-up trucks and liked them.
