The first time I seen the Airtab Vortex Generators was on a CZcams video posted by "2012escapee" (thank you 2012escapee) about a year or so ago. I haven't purchased them yet for my motorhome but I am getting closer as I follow fellow RV'er's who are sharing their experiences with them. I appreciate RVerTV for sharing this video and can't wait to hear how they worked out on a trip.
Now that is SO COOL. You are going to get people asking you what they are!!!! Great idea.
+Shelly Rusek thanks
I'm going to add these to my 12' tall cargo trailer. It creates a low pressure system near the front from the V nose and causes the door to pull out. I found the 80 piece kit on ebay for $98.
Installed on my cargo trailer conversion, gave it some style! :)
In theory, the vortices generated by these devices help to cancel the parasitic drag created by external surface irregularities on the coach/truck/airplane. The idea came directly from aerospace. I wish I had thought to market them myself; I used to install them on airplanes. Enjoy your videos and Scoobs ....
+Super Man great info !!! thanks Superman
Russ , Used these for about 6 months on a KW T680 - did not notice a difference . Running 53 - 55 mph and backing out of the throttle on the hills saved much more fuel . Max tire pressure and side - to - side weight balance also seemed to help . I will try to talk to owners that I see using these . Be Safe
+Rollin' USA thanks
I've seen a couple of videos in the past where people had them on their rigs. Other than that, I haven't seen them being used. I look forward to hearing from you what your experience with the air tabs will be. There you go again, helping us make an informed decision on your experience. Thank Russ, your the best man!
+Sean Ammell thanks sean... i am really hoping for some fuel savings !!
When Air Tabs first came out, I thought. Here we go another Gimmick ! But You can really see a difference in rain, you watch a trailer with them and one with out. And it really does work. Bad thing in a tractor trailer in rain is your mirrors getting spray on them. The drivers with air tabs said it helps with that a lot. As far as fuel, in a big truck if you could save a 10th of a mile on fuel over 120,000 miles that's money in your pocket. Hay, every little bit works !
+RJ's adventures thanks... I was more concerned with buffering and wind turbulence in a bus... this is my second big rig....and if it helps a little on fuel thats a plus.... you would think they would make better body designs on big buses and trucks
great info. thanks for sharing.
+Korey Ratering thanks
Great information and thank you
+ROBERT BURNS thanks robert
I need to put these... 👍👌👌
Awesome!!! I'm living full time in a 30 ft class A. Might look into this for the coach. Thanks
+Kaylie Wilson hi kaylie... I will be testing them out starting next week... i am doing a 700 mile trip thru southern cal and up the coast... i will update the results... thanks for watching
That is what I'd like to be doing, as soon as we pay off the coach we can finally hit the road. For now it's boondocking life :) Good luck on your adventures!!
+Kaylie Wilson thank you
Good Video, thanks, Russ! With gas prices going down, I don't think I'll do that soon. Now, when I paid $5 gallon not to long ago in Cali, I would do it especially when I'm at 5-7 mpg.
+Gene Smith fuel is a bonus... i am looking for better handling in wind
I guess it's time to rethink them since the price of fuel his back up, eh?
gonna check 'em out !!! thanks
+Bill Thomas cool
looks rad....might place on my Casita Travel Trailer - found a testimonial from another Casita owner that said it increased mpg by 1 mpg. Guess it can decrease sway as well.
+Rick Martin they claim they work great on trailers
Interesting.....might consider for my E350....every little bit helps!
+JOHN LAMB exactly the fuel savings even small would be worth it in a RV
VG's are used on many aircraft wings and the reason being is for slower stall speeds and better control of aircraft at slower speeds such as landing! Many "STOL" (bush pilots, off airport use etc)aircraft use them for these features. Big difference is the installation. On air craft the v is forward and there is a gap!..
+M Kidd good info....thanks kidd
looks good.............
+Sparky Nelson thanks
neat..
Thanks for reminding about these~another RV youtuber, 2012escapee I think, has these as well. Everything I've heard has been really positive also. You did a fine job with them by the way! Curious to see a follow up, if you notice a difference in the feel and/or your mileage...no numbers mentioned from other users or on the website?
+RV thereyet? I will keep track of the mileage... I am leaving for a 1000 mile trip in a week or so....that will help
Let us know how they work out for you?
Hello there. Did you ever look into using a wind belt (electric generator) to do the same thing, and to charge Ur battery bank at the same time? Essentially turning the wind belt into air spoilers to reduce resistance by distrubing air flowing behind the vehicle while turning that air disturbance into power.
I'm looking into this now, was wondering if you'd looked into it at all?
How do you measure actual performance of these things? Did you take base line measurements of gas mileage etc. to compare before and after data? Frankly, I'm very skeptical. I think the principle makes sense but I would need measurable and verifiable data before I would stick these things on my RV.
I watched your vid because i was considering the Airtab Vortex Generator; of course, i know you made it a very long time ago. I was wondering if you remember how they worked and did they actually save on fuel? Did they stick to the body and did they start falling off after you started washing the rig? Thanks if you can respond.
yes i still use them onall my RV's not so much for fuel but for wind stabilization and wind drag reduction they are great never had one fall off yet
You should try them in panels instead. V-Spoilers they call them.. So much prettier and practical.. (I tried both of their versions now)
Hey Russ, I have those! Be prepared for people stopping and asking you, "What are those?" BTW I don't think they help much with gas, but do help with winds.
+2012escapee1 thanks...
Think of the reduction in wear and tear on the drive train. 2-4% fuel saving matters big time on big rigs.
Hiya Russ, I'm new to your channel and find it interesting and educational. I wonder why we don't see these on all the big name rv's? Why haven't they installed and colour coded (I'm from wet n windy England) them into the paint job? Normally, anything that they can justify doing i.e. Charging for the parts and labour, they will do. Oh well, I'm sure one of them will wake up to the extra dollars soon. Lol.
+Rich T. hirich welcome aboard..... yes they need to start taking steps to increase fuel mileage at the manufacturers level for sure
Anyone have experience with what they do for fuel economy? I tow a travel trailer and I'm trying to find some way to get better fuel economy. I know it has to do with lack or aero dynamics since I've towed similar weight without huge effects on mpg
Any long term follow up?
Hi Russ,
Any idea if the Airtabs are helping improve MPG? I'm thinking of installing them on my cargo-trailer camper. Thanks.
+Mcconiheflatbrat its hard to say on mileage with a 36 ft motorhome.... the airstreaming on the wind is great buffering and resistance is greatly reduced... i would put them on my bicycle :-)
Russ, I was thinking that is a great idea there. But I was wondering, What if you had to remove them for whatever reason..Would it affect your paint job?? Does it come with removing instructions as well??
+RV Adventurer yes they have removal instructions... its a hard shell plastic cup with adhesive... no worse than a decal... great question... thanks
Oh THAT'S what those are for.. I thought truckers just used them for looks lol
3 Years ... time to notice long term averages ... is there a follow up on this? FYI there is a reported 3% gain just from wheel covers. The fender skirts like on the old Caddys should work on the rear. Toyoda has a video showing their production car(s) of their VG version. In the 70's the air dam was being used as a DIY mod. My thoughts were to use industrial rubber sheet material under the bumper so that it would flex when hit, but stiff enough to resist the wind. MAN has a video where they mention the side mirrors, replacing them with cameras. The average RV roof is such a mess that I am thinking that the issue is hopeless. Happy Trails.
Given time has gone by now, what are your thoughts today?
Hey Russ how are these working for you? Can you tell any difference with the wind and fuel mileage?
huge help with wind and road handling great mileage not so much....i am very impressed with them
When you bought "Breeze" one of the rear outside doors was damaged. I don't recall how you dealt with that, if you did.
+John Bruce no i wont mess with it unlil this summer its not that bad at all
!0-4.
I am staying on the Arizona side of the river near Parker.I would love to talk to you about solar and whatever else you could help me with.
+gary gamache send me a email at rvertv@gmail.com
What type of TV and ant do you recommend and is everything 12 volt?
+BUDDY LIGHT NAXA makes a nice 12 volt TV
+BUDDY LIGHT Yes please~would also like to know...
What's the price per pack?
Uh I don't know about that Russ, seems kinda hypothetical !! Haha
+Virg Valentine can only hope !! :-)
I found them good on crosswinds and when passing Large trucks, dint get pushed sideways as much! on a trip in a small 4 ton rv, I Drove from Windsor UK to Noli Italy and back and Airtabs saved me a hundred miles on my fuel bill, the entire trip was 1927 miles, ive done 7 similar trips like this so far, price of fuel in the UK and Europe is scandalously high, so that is a saving for me of around £190 GBP ($300) in just one year! i use a scanguage 2 to monitor my fuel constantly!
nice info
Hey Dave , where did you install em . I am putting em on my 2 t caravan . Got a wind deflector in build to put on top my tow car . Reckon I will put 10 on front top of van and more on rear sides and roof . Hope it works fuel is killing my travel plans
Extremely skeptical - haven't taken fluid dynamics for a *long* time, but the fluid has to go somewhere. Certainly behind those solar panels, the fluid ( air ) is already so turbulent, that any effect is minimal, at best. Further, the deflection of the fluid outward comes at the cost of a lower pressure area in the back - a vacuum. That will have a slight pulling effect, so it's quite possible to cost MORE fuel, rather than less. I'd really like to see these in a wind tunnel. It would seem that something forward of the main part of the coach that causes cavitation may be effective. It's also possible that these things cause cavitation on the sides, which WOULD allow slightly easier motion through the fluid.
Where did you purchase them?

Speaking of drag, Its a huge drag about the condition of your stickers on your coach. The worst part of having an RV. haha
This guy is why as seen on tv products actually sell
if these things even improved fuel mpg just by 1/10 of one percent, every commercial trailer would have them already.
they only work to empty your pockets of much needed cash.
Russ, any comments yet on the air tabs?
+Merlin they work awesome in wind buffering and other wind conditions... i am happy
They're practical but I don't think I would've put them on the pin stripping. Kinda takes away from the paint job. Just my opinion. Cool gadgets though.
+Me N Grandma yea it dont bother me.... on the stripes are badly faded ...too hard to paint... the goal is performance
I don't know....they're kind of ugly. Any proof that they work? Need some hard numbers to get on board.
Vortex Generators use the same effect that golf-ball dimples use, except on a golf-ball we don't know where the front and back is because the ball is spinning, so we cover the entire ball, whereas on a car or plane we do indeed know where the front and back is, so we only place them strategically instead of covering the entire thing.
Forgot to put them on the solar panels 😂
Ha ...Ha
What a mess mate. Could at least have out them on straight.
lol they don’t work like that you got scammed
