Whistle on highway

[scraig41]

Hello, upon reaching speeds of 60-65 in our Thor A.C.E. we develope a high pitch whistling noise. I had found a post (on here I thought) that suggested the problem was the front grill and suggested an easy thing to try. I cannot find that post anywhere now. Anyone that steer me toward the post I’m talking about or steer me toward a fix would be my hero! Thanks in advance!

Being you have a Thor product you will most likely get better answers on one of their forums. This one is geared towards Forest River products. Two different manufacturers. Sort of like Ford and General Motors.

scraig, I'm confused.
Your other posts state you have a Coachmen trailer.

I have to agree with ResQ. Your question is too specific to a Thor product.

Not your MH or brand, but here is one thread about whistling noise at speed:

Sorry everyone. This was my go to resource in the past. Didn’t think much about it when I switched brands. Must have seen the helpful post somewhere else.

The closest thing to the ACE is the FR3 and Coachmen Pursuit. Both had split grills when they were first introduced. No whistling on ours but a lot of wind noise near windshield area. If your windshield trim sticks up at all that could cause a whistle. Easy thing to try is painters tape over those edges or seams. Then road test.

Almost anything can do it, on my f150 I had a whistle, turned out to be my magnetic mount ham radio antenna, only needed to move it a few inches to stop it. I thought it was up front from the sound, good luck finding it.
