Thinking of buying 2015 Chevy...
I am in the process of buying a 2015 Chevy 3500HD... my friend just finished renting one (out of town) for 2 weeks... he is shopping for a new Chevy too. he tells me that the truck makes a terrible pressure wave inside the cab when the rear windows are down and front windows are up (4-door model).... like a whoop-whoop-whoop kinda sound. if you put the front windows down the noise goes away.
can anyone confirm or deny this claim?
