There was a post a few weeks ago to a Northern AZ CL add that showed one. Coach was a large aftermarket manufacturer of buses, quad cabs, limos, and other custom bodies on chassis purchased from all the truck manufacturers. In the Factory Assembly Manuals it shows the RPO's. Some were just chassis with the steering column and other misc stuff shipped in a box attached to the frame. A google image search turns up lots of interesting stuff which can be followed to the page it originated on. Make sure you get a good title with it.
