Look at what the pro's are doing for your answer. The trucking companies use wind wings and sometimes trailer tails to get better mileage, but I've never seen airtabs on a semi. If they could get a couple tenths of a mpg from airtabs they would be on lots of OTR trailers.
Most people wouldn't notice them if they weren't looking for them. They are on a lot of semi's. All you have to do is look.
