Airtabs are supposed to make an un-aerodynamic vehicle more aerodynamic. They are sold for big rig trucks, but also very good for RVs, they’re supposed to cut way down on the “whoosh” and push when a big truck roars by you on the interstate, making the RV easier to handle. They’re also supposed to improve gas mileage. There were a lot of good reviews on RV forums (not shills) so I decided to make the investment. We’ll see how they perform next time I hit the road!
