Air deflector for truck and trailer
Wondering if anyone uses one of these We'll be putting about 7K miles towing our toy hauler in a few weeks. A fellow I know has a similar spoiler and says he pick up a extra 60 miles per tank full on...

Fun discussion with some animation :B
Personally........
Airfoils on trucks pulling trailers isn't cost beneficial.
MPG increase....minimal at best.
One benefit.....bug line moved higher
Issue is airfoil is just not close enough to front of trailer to be truly effective
Tractor/trailers (Semis) benefit cause deflector is directly in front of trailer, cab/deflector at same height/higher than trailer therefore air goes OVER front of trailer
And they drive 100000's miles every year
