I was trying to figure out why a GMT-400 is called a "gmt400"
and also, why are we OBS.. what makes us original ... i know theirs oobs... or even nbs and nnbs.... thats it going to be after that.. nnnbs? gmt1000?
Because that's what the internal designation for the platform these trucks are built on is called.
'99-'06 is GMT-800 because that's what GM calls it.
'07+ is GMT-900 because that's what GM calls it.
The next generation is doing away with the GMT-### naming system. I just read the other day what it's being called, but I don't remember where I saw it or what it's called. But it will be called that because that's what GM calls it.
The OBS and NBS nicknames began when a lot of the original truck forums were really starting to begin to pop up. Most notably it came from www.FullsizeChevy.com FSC began in 2001. When it began, nearly all of the membership owned GMT-400 trucks or the brand new GMT-800 trucks. It was just easier to type OBS or NBS when referring to these trucks. It may have been short-sighted to use those abbreviations, but that's just the way it played out and the names were solid for another 6 years.
I've never subscribed to the OOBS or NNBS stuff. To me, those are square bodies and GMT-900s respectively. I usually use the GMT-800 designation for the "NBS" and have been trying to use GMT-400 for our trucks, even though they will forever be "OBS" in my eyes.
So many people get annoyed, confused, upset or simply think the OBS and NBS terms, but the fact is they exist and now you know why. Just go with it. Resistance is futile. You will be assimilated.

Also a question...
What exactly encompassed a Z71 package? I know shocks, skid plates and locking differential, but was there anything else? The reason I ask is, I own two K2500s, one for parts, one is my driver. My driver is a Cheyenne model, plain jane. The other one (basically identical, both are 1996, ECLB, same colour, gear ratio, engine, transmission etc.), is a Silverado option, with power windows, door locks, transfer case etc. It was also ordered with skid plates and a locking rear end, unlike mine. However it is badged just as a "4x4" like mine is. I'm assuming it's basically just the same offroad package as what "Z71s" had, but they didn't do the whole sales gimmick thing as much with the 3/4 tons. Anybody have any idea whether this is true or not? I've seen 3/4 tons badged as Z71 but I'm guessing they just put the sticker on there.
The whole history there seems a little hazy and inconsistent. Not that it really matters, I'm just curious.
