Well, we've got some Airtabs. A whole bunch, in fact, of which we'll start with two.
Airtabs--when not painter yellow to match a Corvette--look like this:
If you want them to improve aerodynamics or reduce spray off the back of your trailer, you use lots of them an inch apart. But all I want to do is to do something different to the airflow, so I just put a couple of them in a likely location.
It's a peel-and-stick application, and after cleaning the area well and prepping with some alcohol, I stuck them down and they seem to hold pretty well:
I've got two of them set about three inches back from the windscreen and a bit less than a foot from each side. I bought the paint I'd need to make them a matching silver, but am not going to bother since you can barely see them; the truck is too tall, and it's pretty dark in that area.
You can see them a bit it this photo I took from the front standing on a stool.
.
So far, so good. Nothing to do now but drive around. The wind howl was not routine, so I'll need to have the right conditions before I can even guess whether it I've made things better or worse. I'll let you know what I learn just as soon as I learn something.
