Well, I just called Olympic. They claim the rack can handle 75lbs with the stock spare tire mounts (on a Jeep Wrangler back tailgate with the stock tire). The rack can handle up to 200lbs of stuff on it when you use a swing away tire carrier.

Now the next thing is to call Hummer customer service....see if they know something about the swing gate max weight (ha!)
