The OP asked and actually having had first hand, real world experience I shared {see my earlier post complete with a pic of the rig}. Unless you have some, "Frankly Scarlet"...

Set one up correctly at the rear of the truck, experiment until you find the optimum angle of attack and they work. It is just that simple. I never thought 1.5 - 2 mpg was anything to write home about but over the first year it paid for the deflector. After that it was a savings in fuel costs, not a lot, but free.

:S

That is my thinking. I can buy a used one for $120 and the first trip we have planned if I get 1 to 2mpg better it will pay for it. But very little positive vibes for them.

You're not going to see any savings unless you set it up at the rear of the truck on a bed topper, and have a fairly low trailer. The only reason it worked in this application was it was very close to the trailer. Mounted on the top of the truck cab will be pretty much useless. And it will do nothing with a 5th wheel.
