Look at the turbulance you create with your rig. I have a wing on both my motor homes. Worth 20% fuel economy and abut 10 degrees operating temp. Notice when you go through the rain how much turbulance you create, or on a road with a dusty side, see how much dust you create on the curb side. You should try to get the wind off the front of the trailer and over the trailer smoothly. Just look at the big trucks on the highway. Notice how much effort is made to make it go through the air smoothly.
