I am not so much concerned about the whole sport package bit. I believe air suspension was only standard on the v8's and maybe just the 4.8s but I think all of them had it. I don't think the 3.0's ever had it. Anyways I don't want it because it is just one more thing to break that I really don't need. For what I am talking about towing I really cannot imagine it would be an issue.
