    There are many trucking companies going to the AirTabs and I am constantly surprised when I see them on company trucks. The latests one I have seen are on Long Haul Trucking trucks and some I have started seeing are on tankers.

    We put Air Tabs on our truck. They did not make that big a difference in our mileage but they made a HUGE difference in stability. The 'flow through' mud flaps made a difference of about 1/2 mile to the gallon. We average between 10-10 1/2 for 3 years now.

    The stability/reduced spray are enough to use the airtabs. If they do help fuel economy at today's prices even a minor improvement will result in a payback quickly,

    Airtabs seem to be 1/10-1/8mpg improvement. Their benefit is at least as much in stability and cleaner/drier view to the back in the rain. The mudflaps seem to be about 1/3mpg improvement. Removing the visor seems to be about 1/3-1/2mpg improvement. YMMV
    It's okay if you disagree. I can't force you to be correct.

    If the mudflaps are an inch or two behind the tires I don't see them collecting much air. Mudflaps a foot or two back would be more of a drag.

    The flow through mud flaps cut down a lot on spray as well.

    Just what I saw. Every truck is different. Prior to putting them on my average was 9.5 to 10. Since I put them on it is 10 to 10.5. Those numbers are VERY consistent. They hold true at weights below 6000#, whether I am running the reefer or not. High winds and mountains hit us pretty good.

    Watch trucks that go by and notice what how their mud flaps are behaving... Many people put anti sail holders on the mud flaps which is another indication of how much air they are catching. Either trim them up to match the width of the tires or change them...

    Start looking when a truck or tanker passes you or when going through a truck stop at how many vehicles are using AirTabs they are becoming a very common item.

    We put AirTabs on the truck after our first trip out. (4 weeks out). We really didn't notice that big of a difference with the mileage, (didn't really keep track, but we get about 10.5 now), but really noticed a big difference with stability. We no longer get blown about when getting passed by a semi, and the truck seems more stable in crosswinds.

    We applied then on both sides and across the top of the box.

    2007 KW T600 with a Cat C-11 and 10 speed Ultrashift. 10.5mpg on flat ground and no wind. We usually drive between 62-65. Truck is governed at 65. Mostly driven east of the Mississippi.
