Having been a corvette owner in the past when I got the H2 and now the H1 I always way at fellow "Hummer" owners. None of this only H1 crap. All hummer owners.
With this said, the practice is certainly not as widely followed as in the corvette community or dare I say the jeep community. Really ashame. Guess all we can do is keep up the "community" spirit and hope it catches on.
