airtabs
I was surfing the web and came across these gizmos called Airtabs. They sound like they are the answer to all your prayers. Does anybody have any experience with them?

air tabs work, but dont expect a mirical. my buddy ut them on his 5th wheel and picked up 1 mpg, but noted the biggest improvment was in the handling when passing a rif or in high winds. they basicly work like vortex generators on a planes wing tips, this disrupts the airflow and reduces the low pressure drag area behind the trailer which reduces the drag. depending on what your towing they can make a big difference or a little difference. I would suspect the lowest fule milage in crease would be on a conventional trailer and the best on a truck camper. the trailer has two large drag zones, one behind the truck and another behind the trailer so you would have to fix both to get a biger increase. the camper only has one. a fith is inbetween as the nose of the trailer is closer to the truck reducing the size of that drag area.
