I think that Braebyrn is working off the beaten path here, good for him!
Trailer towing has room for great FE improvement. I know on my car when I pull our little 5' x 10' open grate trailer my FE sucks. I also tend to notice aero changes more than normal. I like the boat tail on the back of the trailer.
For the front look at ways to reduce the gap if possible. I might try building insulation foam (Dow blue Styrofoam) on the front of the trailer. You can shape it if needed and if you make it to tight it will just break off without damaging the truck pulling it. Try to slope the height of the truck to match the trailer, a long slow slope is better (think Kammback in reverse) to keep air flow attached. You might be able to make a sheet of colorplast come off the truck and rest on top of the trailer, this would keep the air attached but allow the trailer to pivot.

Is this what I could do on my setup or is over the top too much?
