The Colorado we bought didn't come with an owners manual to tell us what the truck was. All I know is that it's 4wd, 5sp, 2.8L, it has two full doors and then the two halve doors for the back seat passengers, which can't be opened unless the front doors are opened first.
How can I tell what kind of Colorado we have? We bought it used. on 2005 Chevrolet Colorado
Give me the last 8 of the VIN # and I can get you the info in a PDF format. I can also get you the build information.
