Air Tabs(vortex generators); has anyone used them?

[Senior Chief]

Hey boys and girls!

Haven't spent very much money on the motor home this week, so to rectify that unusual situation, I ordered a set of Air Tabs
which are little stick-on vortex generators for the rear top and sides of the MH. They are said to significantly improve handling and mpg.

I talked with a fella a couple years ago who had put them on all his freight trucks, and had just put them on his motor home (which was where I saw them and asked him about them). I forget the details but I was impressed with what he said were his results, and it stuck in my mind to try one day.

Has anybody here used them on their own MH and if so do you feel they are effective at all?

I should have asked before I ordered them I guess, but heck- impulsive and foolish purchases are my specialty!

There is an individual on Classic Winnebagos who, for his Class C, says:
1) Went from 9.8 to 11 mpg
2) Gets better mpg with them at 55mph vs 60mph.
3) They help keep dirt and grime off of a toad.

Basically creates a 'boattail' aerodynamically... was looking into them myself.

Somewhere, I have a template to make them out of aluminum..

Hey Chief:

I just wondered if you have anything to report on your AIR TAB installation in 2009?

Well, we think they worked very well. They created markedly better handling for our motor home, especially in strong headwinds and when the big rigs blow past.

There is no virtually sidewind effect now- its a rare situation that makes you feel like you need to have 2 hands on the wheel.

The mpg effect wasn't really measurable, since we did some other things at the same time to help with the mileage.

I'd buy them again.

Pictures or link please?

[Senior Chief]

I don't know if I can load any pictures- we are on a S-L-O-W internet connection here in the backwoods of south Texas.

Here is the company link. We painted our Air Tabs blue and beige with Krylon Fusion paint to (more or less) match our MH paint. Looks pretty good- even got a compliment on our "fancy scallop decorations"!

Cost just under $200, IIRC to do sides and top.

Thanks fellow, I got that one now. Am going to get some of them. Thanks again, Dan
