Well I pull the trigger to and install Air Tabs on my camper. Hoping to cut the wind noise around the passenger door and reduce bugs. We will see how it works. ART
PIANOTUNA here are the photos on my truck. I went off one of the wings on the bottom goose then snap a caulk line. They need about 3/4 inch apart they recommended a thumb space. So that is what I did they say 3 per foot, but due to how the shell is laid out I had a larger gap on the outside ones. But they should not touch.
Steve, I have not yet, just the mileage tracker on my truck. I was getting around 10 or 11 before, coming home when checking it read 11 and 12. So millage is yet TBD. I'm going to add these towards the rear of the camper like stated on there web site. So that should reduce the drag. This is a test in progress, but as I mention above I'm very happy the wind noise as been eliminated so to speak. And bugs reduce ALOT. ART

Thanks Steve68 for the explanation of how air airtabs, helps me to visualize their effects.
I would like to streamline the aerodynamic mess on the roof of my camper and was wondering how Airtabs might work on my camper if I ran a horizontal line of them approx. where the camper clearance lights are. All constructive opinions and ideas would be appreciated. I hope the OP doesn't mind me asking.

Those are called "vortex generators". Aircraft often employ them:
If you have a sunroof, you probably have a sawtooth or castellated edge that flips up at the front of the opening, too - without it, turbulence would create an annoying, pulsing, "thud" as you drove at speed. Same thing - a vortex generator.
A vortex generator puts energy into the airstream, causing the trailing air to "spiral" (a vortex). Since it has more energy and is spiraling, the air can't/ won't devolve into a turbulent mess, creating drag BEHIND the surface - it will flow/ spiral PAST the trailing surface, only becoming turbulent when the vortex energy dissipates much further back.
So the idea is that you're creating a smoother airflow over surfaces and past trailing edges, which creates less turbulence behind them.
I'm really interested to hear what the OP finds - putting vortex generator on the underside of a TC cabover seems like it would generate vortices aimed right at the vertical front wall of the camper - a worst-case scenario, aerodynamically.
