Looking at getting a travel trailer, and dreading how horrible the aerodynamics are going to be. I've been researching trailer tails a bit, but also found these "Airtabs" things.

Does anyone have experience with these? I know there is some basis to managed turbulence, like golf balls flying 20% farther with dimples, for example. At $220 a kit, I'm thinking these might be worthwhile if they actually help a little. What does anyone know or think?

Lol, j/k. I have no input on that other than it looks like something that is on a Pep Boy’s shelf and stuck on every ‘90’s honda civic.

A lot of major trucking fleets use them so there must be something to it.

I put them on mine last year but only on the roof because I don't have the smooth fiberglass sidewalls so they couldn't be attached to the sides. I don't know how much they helped since they're only on the roof and I had only towed the trailer once before they went on, but for the price I thought it would be worth a try. Instead of ordering the kit I figured out how many I needed and ordered that quantity so I think it's only about $100 I have in them.
The main reason I added them was because I read comments about them helping minimize the trailer being pushed around by passing vehicles.
