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...

Have you used one of these?
There is nothing out there that will give you a 20-25% improvement in gas mileage (assumes a typical 250-300 miles per tank).
