I tried this.

I think you are being too aggressive for practical use. Your skirts look to be 3-4 inches above grade.

Mine were six inches above grade (on a similar vehicle) and they caught every bump in the road and eventually tore up even my indestructible ripstop conveyor belt material.

But they did have a positive effect on MPG.
