Head Wind

[ChuckS]

I have a jayco 196 and tow it with a 08' Chevy 1/2 5.3 with 3.73 gears. I was checking to see if anyone have used a wind deflector on top of there turck, if so did it help with towing?

Thanks,
Chuck

Although I dont have a wind deflector on the top of my truck I do have a cap on it and you can see from the bug splatter where it has forced the wind to when on the highway. In my opinion if you dont have a cap on the truck a wing will be a waste of money as the air will start to drop before it clears the trailer.

I don't watch much TV, but I do remember watching the show MythBusters about a year ago. They did an episode on those wind deflectors and actually found they caused more wind resistance than anything.

The theory went that in order for these wind-deflectors to be effective, they would have to be mounted literally an inch away from the front of the trailer - otherwise a natural vortex/downdraft is created between the trailer and the deflector creating more drag than if you didn't have the wind-deflector installed.

Now - to be honest I've never had one, but those two knuckle-heads on that show seem to get it right every now & then!
