Going down the road over 50 MPH or so I am getting a buzzing sound around the left front of the windshield. I have tried to isolate it but can't. I thought it must me the plastic round the edges but I put my hand on it going down the interstate and can't feel it buzzing anywhere. I don't have any lights on top and now think it is coming from the wheel well or under the hood. Anybody else had anything like this??

try to tape around the windshield with blue masking tape. It could be an air leak at the seal?

If its under the hood, look for the black steel tubing that runs along the top of the firewall. This is held in by plastic clips and on my rig, the tubing had popped out from the clips in certain spots and vibrated at high speed/RPM. Someone else reported this on this site so I checked out my rig and hand the same problem.
