Good morning everyone, hope you are all well. So today i wish to ask of folks is about Dash noises while driving. Being a retired mechanic that for YEARS that did “squeek an rattles” im finding myself driving down the road to a point of disttaction trying to determine the origin of these sounds🤪 so i have located some however what remains is what sounds like a deep hollow kind of noise that comes in an out depending on the road surface. At times i think its from my roof mounted dish, an others like the dash mounted ac unit. I have shaken an wiggled componits and all seems secure, on my last trip i saw where the gennys power cord had been thumping a metal support(i havent drivin it yet to confirm a repair) so i thought i would throw it out to everyone in hopes of determing another direction. I bought my rig used so i dont have any past history. Anyone else get distraced while fixating on noises? Are your rigs normally quiet? Perhaps i just need to let it go, yeah NOT! Thanks all

They are all subject to noises, lots of components etc everywhere. You don't state what model, year, type of RV you have....

Might be a loose nut behind the wheel?

Hahahaha....

If you have the retractable TV antenna make sure it's down all the way and that the rubber bumper it rides on is intact?

I had that problem. It was a plastic AC duct rubbing and squeaking. The hollow tube amplified it to a huge sound.

We wish.
Even among the same model and year, these Coaches are hand built and no two are the same. That's why they call them "snowflakes".

We have a 2008 Monaco Knight 40DFT. It has a shrill whistling noise up front. Sounds like it is related to vehicle speed (gets slightlyhigher pitched as speed increases), and maybe to the in-dash A/C fan. It might be the door seal. It's one of those noises I have to ignore, or it will distract from driving safely. One of several... of anyone has ideas about how to narrow down and eliminate these and other noises, we are all ears.

Do you have any after market antennas on the roof? Some that have curls are prone to whistling. A piece of heat shrink over that part stops it.

Squeaks and rattles drive me berserk.
If you have electric shades/sunvisors try extending/dropping them a tiny bit.

On my check list it to tighten my electric awning before leaving. The can rattle if a bit loose.

The fold down antenna can rattle.

My wife has spent time chasing the noise makers. I only do this on a clear highway with little traffic. I hate it when she does not have her seat belt on.

Door rattles have driven me crazy more than once.

More info on your RV might help, model, year etc.

You may have the noise we had on or Windsor. Our howling noise would get
so loud you could not stand it.
Mine had some foam glued in the hollow channel of the door awning leading
arm. Fortunately, I saw the foam coming loose and finally blow away and soon
the noise started. New foam and all is quiet

2003 Holiday Rambler Endeavor 36 ft.
The noise starts after 45 min of driving and it doesn't matter if windows are open or closed, if generator is or is not running, a/c on or off, vent or no vent... As a retired mechanic I spent years doing wind and whistle, on cars and trucks for Ford.

One such vehicle was a full size Bronco that I had to remove the entire dash, seats, and trim, tape off all found openings, load the vehicle atop a flatbed tow truck and have driven at Hiway speeds while I was in the Bronco talking with the driver on our cell phones... the noise was due to a failed spot weld that would start to vibrate at 62 MPH that would telegraph thru the entire firewall area.

I don't believe I will go to this extent to fix this problem, however if someone has had noise issues around the the front dash/cap area could help in pinpointing possible similarities, Thank you
