CFD of my Semi Truck Boat-Tail

Don't mean to bump an old thread but it's the only one I've found on tractor trailer boat tails.

I'm sure most have seen the new trailer side skirts they are using I pass them every day on the highway. I've also seen more and more tractors using smooth rear wheel covers. I really didn't pay much attention to it til I saw a trailer with a partial boat tail. Since then I've seen about 3 or 4 boat tails fixed onto trailers and I was kind of impressed. Anybody know who makes these? This could revolutionize the trucking industry if there is a significant increase in mileage. Especially if they are fairly easy to remove and install for loading and unloading

This is the one I see the most on national fleets loading out of Laredo.
