A follow up on how Edward did the install..

Received September 12 , 2017

Hello Jack,

More on my installation.

I made sufficient 1/4″ X 2″ X 4″ blocks to fill all of the valleys on the siding then cemented them in place with caulking compound. I cut the drip edge to length and installed the air tabs on it before applying the finished panel to the rear of the trailer which had been prepped by running two parallel beads of caulking from top to bottom. I them used self tapping round headed sheet metal screws to fasten the panel to the trailer side, water-proofing each screw with clear Goop. Lastly I filled the leading edge of the aluminum with a fairing of weather-proof caulk.

We have now been about 2000 miles with the tabs and as I wrote earlier, I LOVE THEM!!! It is almost hard to believe how well they work for eliminating the vacuum of passing trucks and the associated swaying of my trailer. The only exception is when an overtaking semi passes me during a left hand curve but now I can usually time that to avoid it. I also cannot yet comment on wind effects but I will when I get some experience. Today we are avoiding Irma by staying put in a campground in northern South Carolina. That’s why the photos have grey skies and the trailer is wet.

Note: When asked why Airtabs on only two sides, Ted said he ran out of time to finish the installation before leaving on his trip to South Carolina. But will finish the install on the curb side when he returns home.

Airtab,

I installed the air tabs on the driver’s side and the roof. For the trailer’s corrugated side I used a piece of white drip edge with 1/4″ thick pieces of wood to fill the hollows and caulked the leading edge. I couldn’t be happier with the results!!! Except for when a truck overtakes me while on a left-hand curve I no longer feel any effects of the trucks, wonderful, wonderful, wonderful! I don’t even care about any gas mileage savings and would have paid well over $1,000 for your product had I known how well it works for passing trucks. I no longer fear their approach in my mirrors. You’ve got a real winner and I am surprised by how few I see on other trucks and campers. Thank you, thank you, thank you.

Airtabs and Advanced-RV

May 15 2017

Advanced-RV, a builder of custom Mercedes-Benz Sprinter Class B motor homes in Cleveland, OH, recently tested Airtabs on their Super Stealth model, which is built on the Super High Top Sprinter chassis. Compared to the standard Sprinter, the higher, smoother profile of the Super Stealth causes different aerodynamic flow lines, which change the vehicle’s response to wind disturbance, such as crosswinds, and other airflow interruptions, such as truck traffic. The installation of Airtabs on the Super Stealth noticeably improved the ride, stability and handling of the Super Stealth.

Advanced-RV (ARV) is on a continuous quest for improvement in all aspects of their motor homes, including handling. When a client reported improved handling of his new Super Stealth with Airtabs, the ARV team set out to systematically evaluate it.  With the help of engineers from Neundorfer, Inc., which conducts gas flow modeling and optimization, through both physical and computer modeling, the engineers at Advanced RV evaluated the design of Airtabs and determined they would break up the uniform rear eddy currents and possibly improve handling.  Subsequently, they installed Airtabs on a demo Super Stealth model, named Runaway, with the support of Airtab and according to their installation recommendations.

The owner of ARV, Mike Neundorfer, who had driven Runaway for about 6,000 miles before the Airtab installation, drove it another 7,000 miles after installation of the Airtabs, experiencing headwinds, tailwinds and high speed truck traffic. The conclusion, although anecdotal, is that AirTabs made a significant improvement in the stability of the Super Stealth.

At Advanced-RV, where every motor home is unique, clients are invited to be part of the design team.  Each motor home is built on a foundation of integrated technology, including all electric Lithium batteries and auto-charging system; large tanks; diesel heat and on-demand hot water systems; and, a single, integrated color touch screen information and control system.  When Mercedes Benz introduced their Super High Top chassis, Advanced RV designed the high ceiling, Super Stealth model, with ducted air conditioning.  Airtabs is part of its continuous improvement.  Advanced-RV is a Mercedes Benz Master Upfitter and builds custom motor homes on 2500 and 3500 models of rear wheel and 4×4 Sprinter chassis. They build on 144” and 170” wheelbase models and all body configurations

2017 Starcraft Launch Travel Trailer

Received March 23, 2017
Hello:

I installed Airtabs on my 2017 Starcraft Launch travel trailer last year.  Please note the attached pictures.  I tow the trailer with a 2015 Ford F150 with the 3.5 Eccoboost engine.  I have been testing the tabs for several months.  By far, the most significant improvement in performance I have seen is the lack of any kind of sway when being passed by, or passing by any large truck, trailer or motor home.  The difference is amazing!  I have also noted a small improvement in gas mileage; from around 9.5 to 10.2-10.5, depending on wind and speed.      It’s a great product.  Inexpensive, easy to apply and with astounding results.

Jack:  Two trips ago I received my air tabs for my 2016 Winnebago Winnie Drop 1780. Prior to installing these we took two longer trips with the trailer and we averaged 8.1 Mpg over the course of two trips. Since installing the airtabs over the course of two additional trips we have averaged 9.8 MPG. We really haven’t noticed any difference in the swaying of the trailer but since it’s relatively small it didn’t sway much to begin with. But the Huge gain was in the fuel economy.

Respectfully,

Robert, Oklahoma
