Hummer Forums by Elcova - Towing Package?

I own a '05 SUT and I just bought a 31 ft. thunderbird formula boat and want to know what I can do to my h2 so that it can handle the 9000 lb load. I know that thats more than my h2 is designed to handle but I'm only going to be pulling less than 45 miles at the most on an avg. basis. I am also running 22 in rims and 37 in tires but the tounge weight of the trailor doesn't seem to be a prob at all. ( I don't have air susp but I bairly can see that my rear end dips at all) I am hesitant to get a super charger but the I think the drivetrain needs to be beafed up. Any ideas? Also its a three axle trailor with heavy duty breaks.
