Interesting project! I was just looking at your cab faring idea. I think you want it the way you have shown it, but I see no reason not to extend it all the way down to truck bed, and outward, as shown, to full width of trailer. Looking at what the long haul trucks have, it is pretty much that way. With the short setback from trailer front to hitch pin, and the rounded front of the trailer, you should not require a lot of clearance. The most likely interference will be at top, when the truck rear wheels hit a dip. That will close the clearance very quickly. You could use a "soft" edge to the faring to avoid damage, then if you see signs of contact, you could simply trim off a bit.
