Guy's, I am now on my 6th C, presently a 36' Seneca. I have had the same basic problem with all of them...plus anoying rattles around the doors. I have just accepted it, anoying as it is.

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.

I have a set I purchased off EBay. They work well. But not sure they reduce noise.

You probably already know this, but just in case.... If any part of the noise changes when the pavement changes, it's tire noise. I'm not real familiar with the layout of the Kodiak cab, but it looks like the back of the wheel-well may be shared with the cab. Undercoating the back (and maybe top) of the wheel wells may help. Or you can use a sound-absorbent mat material under the floor mats / carpet in that area. Or both. Google for 'Dynamat' as a start, but I think there are less-pricey alternatives that work about as well. It's commonly used by auto stereo installers.

An old mechanic's trick for checking weatherstripping is to put a dollar bill into the suspect area, close the door, and pull the bill out. If it comes out with little or no resistance, the stripping needs improvement.

Thanks for the response. I am to pick up a set of the window/door deflectors today. I'll install them when I get the bigc back from warranty work after the shakedown trip.

I am looking for a bug deflector for the hood but no luck so far. I want the air coming over the hood to tumble rather than a stright line.That may help. tks, bumpus4

You may be right. This is my first c and I didn't know what to expect.
I pulled my tt with a ram and the only noise i had was passengers and the turbo spooling up. I may just be expecting too much from such a mass pushing air around the cab. You can hardly hear the engine at idle with the diesel genset running and the c setting still. tks, bumpus4
