Yea, "GMT" covers a large range of vehicles/trucks. My girl, Linda, owns a 2002 78k miles GMT360 Trailblazer and I own a GMT800 2005 Tahoe Z71. That is the newest I would own. I belong to a forum that covers these and GMT900 and newer. To this day, Linda misses her favorite GMT400 truck that had to go to get the TrailBlazer.
