Agreed. There is more room for transporting cargo in my wife's Envoy, than in my H3, but I didn't buy the truck for that. I just wanted a Hummer, and the H3 won over the H2, simply because of it's lines and styling. I like to call my H3 a "Sports Truck", similar to the 'Sports Car', because it looks like it will carry a lot, but the perception is deceiving.
If I could, I would have gotton the Original H1, in the Military configuration, but I just didn't have $150,000. available.
I think a trip to the dealer may be in order today to see if this idea is being developed.
