Buzzing in the front of 2020 Hurricane
We have a 2020 Hurricane 29M that has a bothersome buzzing noise above 40 mph. As near as my wife can tell while seated in the passenger seat, the noise is coming from the lower right front corner. It is difficult to pinpoint but seems loudest at the right hand kick panel under the dash. This is where the sound system speaker is located but I’m pretty sure the noise is not coming from the speaker itself. The noise is definitely speed/wind related and even changes slightly depending on outside wind direction. It also modulates a lot when we are close enough behind a semi-truck to be in his slip stream.
I have been experimenting by stuffing towels in the various cavities behind the grille and also by putting masking tape around all external seams that are in the wind flow. Since this is the area where the chassis heater is located I have also experimented with all heater/ac settings. So far this has all had only a very minimal effect, or maybe even no effect. I am now in the process of stuffing and masking features inside the R/F wheel well. I WILL find the problem eventually but I am posting this just in case someone has the same problem and has already solved it. I have found other threads here about wind noise and as near as I can tell they are all relating to a high pitched sound. This is definitely NOT a high pitched sound and definitely IS speed related, and can only be described as a low frequency “buzzing”. It could very well be something unique only to our coach, such as a loose panel or some other component. Thanks in advance for any help.
I like to travel, but I also like to get back home.
