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...

For them to be of any benefit two things must happen.
First, the deflector must be VERY close to the trailer, as in inches count - pull a TT and put the deflector on the cab roof and at best you move the bug line up. Mont it on the rear of a pickup shell, or suv and that is different story.
Second, the aerodynamics the front of the trailer must truly suck. A rounded front won't net anywhere the improvement as a flat wall. Dodge_guy has about the best setup for a deflector, 3-4 feet gap to a flat wall.
