Fresh off of 10 days in mine, this topic looms large for me. Wind noise in my setup (Ram 3500 + flatbed Hawk) is pretty substantial. Now, it's certainly not so bad that you can't enjoy a podcast, but its very noticeable.
i'm wondering if larger trucks like tundras are inherently quieter than the little tacomas.... larger cars seem to be much quieter than smaller ones - from engine, wind, and other noise... they seem to absorb sound better, and probably are better insulated against sound, much more cush.....
Maybe. Hard for me to compare. I think the larger frontal area of the flatbed model + higher mounting may be contributing factors for me. If I built over again I'd pay more attention to the height of the flatbed and try to find one that resulted in a few inches lower overall height.
Are diesels quieter than gas engines? I've never even ridden in a diesel car or truck......
Nope. But the wind noise is far more bothersome than the soothing growl of the engine.
