That's big enough to haul everything I own and have room left over to sleep in it 
My dad used to run a roof wind deflector with his fifth wheel, claimed it worked, but then he said deer whistles worked too

now, my enclosed car hauler front is like a sail, and these deflectors would be SO far away to be useless there too. thought about adding a nosecone, but they want a couple arms and legs for them.. don't tow it that much now

How many wind deflectors do you see on pickups. This should tell you how affective they are. If they worked there would be lots of them in use. As mentioned earlier, trailer manufactures have done lots to make them more aerodynamic.
