I feel the GMT800 is superior to the GMT400. I've been under the hood of my '400 far more times than that '800. The '800 hasn't left me waiting on a tow truck either. (Yet) They're very comfortable and run really smoothly. I'd love to find the GMT800 version of my '89 K1500. If I did, I'd snatch it right up. Have only seen one similar. It was a 4.8 and I hadn't quite gotten my monies worth out of my '89 at that point.

Here you go. 2006 and 2005 were considered the best GMT800 years and in Oregon, we have no rust. This has been up for a while because of his asking price but it is in great condition and very low mileage. I have to agree that the GMT800 series have the most comfortable seats, by far!
