He did, but that was a few years ago and it would require a lot of work to rise them up to today's standards, as regards to the detailing of the model, shaders, baked shadows, sounds, cab interior, working windows and doors, etc. He may not wish to invest that kind of effort in an old model.
The E9 was a suggestion of mine, and I sent Dick the skins. He did a very good job of replicating the UP classic E9 set. That being said I did do some updated photo-real trucks for it. I can make them available if folks want them.
