Thanks Jason, good to hear I am not the only RVer here.
My 5th wheel is a 1991 model with less than ideal aerodynamics.

It is a slick side and the belly is relatively clean on it, which are both pluses. I figure with that sloped front if I can fair it from the top of the cab to about 70% up the slope and within 6" of the trailer, I'll see a significant decrease in drag. Now it is about 6' from the top of the back of the cab to the trailer face. Of course I'll be dealing with difference in width as well, the cab being about 5'6" and the trailer at 8'.
