Is there such a thing as Kenworth T-6000?

I have sort of been looking around for a box truck. Somewhere around 2003-04. I have found several Freightliners M-2 and Int. 4300. I seen a fellow have a 2003 Kenworth T-6000 (that's the way he has it listed) I did a google search and cant fined a T 6000 only a T 600. This truck is rated at 26K. I have never seen a Kenworth rated that low. I want to stay under CDL. He says it has a 10k front axel and a 20k rear. It has a 3126 Cat. 295K miles. He is asking $14k for it. I presently have a FL 70 with 8k front and 19k rear. Under CDL. What is your opinion on this truck as compared to others?
