Wind noise when towing - under powered

ReviewI just bought a 2007 2500 6.0 Suburban to replace my previous 8.1. The 6.0 is way underpowered and gets about 1.5 mpg less than the 8.1 during normal driving and .5 to 1.0 less when towing. The worst part is the wind noise when towing. I had it "fixed" with a new engineering upgrade to the weather-stipping and flip gate glass and it still is really bad. The GM engineers said that this is a good as it gets and that since the noise is only during towing that's the current fix. Good answer for a $50K vehicle! If you tow, beware.This truck is severely underpowered and the wind noise will drive you crazy.
