Yeah this is exactly the type of thing I'm looking for. Do you have any contact info for Pacific Truck Equipment?

When you talk to them, you need to be very specific with dimensions on what you want. For the most part, my bed fit right on my truck, no extra work needed.
I ended up with 2 problems that I wish I could fix. The first, my wheel well opening is not centered on my tire, fixable, just not what I want to do.
The other is that the middle/horizontal door opening is not vertically deep enough. It could be opened up at least another 4 inches without even coming close to the tire during bottoming or a blowout.
