If you have a flat back trailer, that's the biggest problem, not the front. Flatbacks create a vacuum which tries to pull the trailer backwards when its trying to separate from the air flow. When I had a flatback, I used a deflector on the rear (not front) to direct the air flow down the back of the TT to break up the vacuum (also keeps the back clean). My Trail Cruiser is much more aerodynamic in the front, back and underside.
Did the deflector on the trailer do anything for fuel economy?
Probably, but I don't pay attention to mileage anymore, you get what you get. Made it easier to tow and no swaying at all. If you worry about gas mileage too much you don't have much fun RV'ing. I stick the nozzle into the filler tube of my 42 gallon tank, go sit in the truck til it kicks off, hang up the nozzle without even looking at the pump.
