I have owned one for many years. I put it on my 1 ton dually long bed this year, after storing it for a few years, to see if I could get the air over the top of the 5er. My deflector is adjustable and it automatically settles back towards the 5er as you gain speed. It's set for the highest deflection but still by the bug line, it doesn't get over the top of the 5er. The bug line is a nice arc about a foot from the top of the 5er. I never looked at mileage with it as I bought it for a different use when we had the TT and that was 3 trailers ago. So IMHO don't get one unless you want to keep the bug line higher up on the front of your rig.
