Wind deflectors

[dondford]

I pull a 20 foot trailer with my 2005 4R; I have seen advertised wind deflectors that mount on the back of your TV that they claim improves gas mileage a good deal. Does anyone have real world experience with a wind deflectors?

Thanks,

I asked the same question to my friend who tows a 5600lb trailer. He told me that there's only a minimum difference. So I guess it varies to each person whose uses a deflector, and there are several factors that affect fuel mileage aside from the drag effect of the wind.
