RV wind deflectors????????

On TTs with nearly vertical fronts as those who posted pictures have they do work. I have one mounted on a headache rack on the front of the bed of a short bed pickup and gained 1 MPG pulling that style of TT. The optimal setting was the trailing edge up apx. 1 degree from the line along the plane of the deflector to the top edge of the TT.

Hmmm!!!! Or what has happened, happened because of a single change!

I, like many others, used to see a few of these years ago but see very few these days. That alone should give you some pause.

Ditto.
I used to see them in the 70s and 80s, and maybe early 90s... and none for at least 20 years.

I had one, non-adjustable, for my fifth wheel, attached it to the cargo rack on the back part of the crewcab. I did see slightly better mileage when towing but it was such a pain to put on and attach securely that I left it on while out touring when we were travelling, wiping out any potential gas savings. It did, however, move the 'bug line' way up to the top of the fiver, so some benefit there. I bought it used for $75 and sold it a few years later for $50.

so looks like 2 who have actually used the air dams. The O/P was looking for actual usage not I think, opinions are like ...H.... we all have them.

Ya, mine is adjustable and can be laid flat when not in use. Yes, I too had very little big splatter on the front of the trailer. Which shows that it works. It was also way easier to clean the front after a trip.

As one of the two {see my first post complete with a photo of the rig and a detailed explanation of how and why it actually worked for me} who has had, and shared actual, real-world experience this thread has convinced me that "Denial" is not just a river in Egypt.

As noted above one of the additional proofs that a deflector properly set up works is the absence of bugs on the front of the trailer. Don't know how the deniers can explain that one but I too never had bugs on the front of the rig when running with the deflector. Maybe it scares them up and over the trailer and has nothing to do with wind being directed. :S

LMAO :B

Well, the Flat Earthers don't understand why people continue to deny that the earth is flat when they can demonstrate it so well. Would that be denial too?

Personally I can see how your setup would work better than most, since the wing is far enough back that there might not be enough room for the air to curl up and over, or around the sides. And bugs being further up the trailer mean very little when it comes to air currents, since we are talking about air currents and not bugs.

And people who are convinced that the latest and greatest gas saver they just put on their vehicle works, will usually find that it works great. They unconsciously drive a little easier, use a little less throttle, back off just a touch more, et voila' better gas mileage due to the latest gadget.

Wrong app for a reflector for the OP. Notice the successful claims are not 10 feet away from the trailer on the roof of the truck cab.
If you get one though, it needs to be chrome and look like an old skool dragster!
