We would like to know if anone has had any real experience with the metal or fiberglass wind deflectors made for the roof tops of SUV's. I'm looking at ease of set up and results. I realize that everyone travels through differant terains so the mileage would vary, but anything you could tell me would be appreciated.
Thanks and happy traveling.

I read somewhere that according to wind tunnel tests, it takes 80+ MPH to get much benefit. Don't know what actual results would be.
My experience is to get better milage (if that's what you want) slow down and take your foot out of it. I don't drive over 60 and don't use any more peddal that I have to. With our 2 cars and PU I have gained from 10 to 25 percent. The way I figure it 10 percent is about $.30 per gal. at the pump.

We had one years ago on a blazer and a 21' trailer. Never saw any improvement in fuel economy, did see the bank account go down, and it did have the benefit of keeping a few bugs off the front of the trailer...but you still had to scrub the deflector.

Don't waste your money in my opinion.

Also, a great big HOWDY to a new member.

This subject has been discussed on just about every RV forum on the web, and there are over a dozen RV forums at my last count..

Some folks like them and some don't.

But unless you understand how they are "Supposed" to work, you are wasting your money installing one on your tow vehicle..

Here are a couple of links to other discussions on the subject of wind deflectors..

Wind deflector

Maybe reading what others have to say about their experience with wind deflectors will help you in your decision..

Best Wishes,
John
