Has anyone had any experience with AirtabsAirtabs? They are suppose to improve both handling in cross winds and gas mileage - almost too good to be true. I would appreciate hearing from anyone who has experience with these.

They save trucking companies a lot of money on fuel each year. I was told that they paid for themselves after about 100,000 miles which was about 6 months for my friend. As fuel prices increase the ROI becomes even shorter.

I have them. My fist-hand experience us noted below.

I cannot speak to fuel efficiency gains - there are way too many variables for one vehicle to be able to do that.

I can speak to the change in air flow and handling improvements. The rear of my MH is significantly cleaner, which is objective evidence of a significant change in air flow. Another piece of objective evidence of change in airflow is rear camera visibility in the rain at highway speeds. My rear camera is now usable in the rain, and it used to be totally useless. Subjectively, I have noticed significant handling improvements in high winds and when passing (or being passed by) large vehicles such as tractor-trailers.

The improvements one gets kick in somewhere around 30 - 40 mph or so - below that, the air is not flowing fast enough to make much of a difference.

I have used them on a 27'C and a 31'A and my impression is the same as Westronics. Painted to match body colors they don't really stand out.

I have them on a 28 ft car trailer. I got them to help with a sway problem, and they did help a lot. I got between 10% and 15% better fuel mileage as well, towing at 65 MPH. Going from 8.5 to 9.5 doesn't sound like a lot, but hey - everything helps!

I only have one question; if they are so great, why do the major freight haulers and over the road buses NOT use them? Considering all the interstate highway driving that I have done, I can honestly say I have never seen them on any vehicle.

They have pre-appled sticky tape covering the entire back. Peel and stick. Be sure you get them facing the right way. On my first rig I got 5 applied before I realized they were backward. There is no chance to remove and reset them the sticky will be ruined.
