Loud Noise in cab when windows down

[cnolan001]

I just got my truck 3 days ago. It’s a 2009, 1500 Crew Cab with a sliding glass window. I put the back window down and had a horrible loud noise. Is this normal ? Has anyone else experienced this ? Please Help.

It is wind noise. I have had the same thing on several vehicle when you just roll the rear windows (both) down. There is actually something in the owners manual about it.
