I did quite a bit of research on H2 tire carriers before I purchased our H2. I ended up with the one the dealer (Parkway Hummer - Valencia, CA) offered because it was the only one that opened with a finger latch (no bolts or pins to pull out). I tried to envision my wife with an arm load of groceries using one hand to open carrier and swing it out to open the rear hatch. There were less expensive carriers but seeing some of the other types on H2's I'm very happy with ours. The dealer wanted $1700 and I told him that was ridiculous. He finally told me their cost was $1295 and sold it (and installed it) for that price. I've seen the same carrier at Predator Motorsports
