Forums are a big help when it comes to aftermarket companies trying to decide whether or not to make a product for a certain vehicle. Actually, I know of a couple of companies who frequent this forum. The reason is because this seems to be the best and most informative and most visited forum out there for the HUMMER H2. However, it is people like you who cause these same manufacturers to stop thinking about developing or producing products and turn their focus to some other SUV - like the Lincoln Navigator / Cadillac Escalade / Ford Expedition.
And regarding the VERY LONG signature line... At least mine lets people know the different products available on the market. Yours just seems like someone who had a complex when they were younger, or maybe its that "making up for other departments" thing... Except for the H2 and the SL600R...
