I tow a 24' Haulmark enclosed trailor(Flat nose) with an 04' Suburban. Occasionally I can hear the Burb's back lift glass sucking air... Usually at highway speed. I have considered buying a temp wind deflector for the Burb's roof to help with this and improve gas mileage a bit. So far it is getting 11.5 mpg which I hear is fairly decent already.
The sucking sound is not constant for me but I can see how it could suck your cap glass up if it is not completely secure. For what it's worth the wind deflectors run in the $ 200.00 range for a decent one. I am sure it would pay for itself with gas savings in a summer. Good luck,

The PY Online Forums is the largest online gathering of Pontiac enthusiasts anywhere in the world. Founded in 1991, it was also the first online forum for people to gather and talk about their Pontiacs. Since then, it has become the mecca of Pontiac technical data and knowledge that no other place can surpass.
