Does one of these really help??

You are kidding right?

well according to the website etc they say it will give you 10% better fuel economy and I just wanted to know if anyone has used these and had the same results?

LOL...
I'm sure if you're drag racing with a trailer in tow it might help... LOL

It has to be true, it's on the internet.

It probably says UP TO 10%.

lol then why even have them??? lol

That thing will create more drag than anything.

Because people buy them or consider buying them. They're great for keeping the bugs off the front of your trailer though

You forgot one...

The same reason they make spoilers for neons and hyundais. Some dumbass will buy them.

Y'all are so mean, coulda just said "no, they're full of shit".

Instead you gotta make the dude feel retarded.

I think if you put a GIANT roof cap on like an 18-wheeler has there is the potential for savings there...outside of that. Not so much.

If you do go that route with the giant trucker cap let me know...we can make a bunk bed outta your back seat! So much room for activities!

:lmao: at the activities

haha yea true that but our bullies are teenagers and young children not grown men lol even though they think they are grown sometimes.

Ah, indeed BDT, I've seen those threads... poor guys probably end up deleting their accounts.

Pic's not working for me but if you're referring to the roof mount air deflector it won't help unless it's within a foot or two of the trailer. Really only helps for 5th wheels. A bumper pull will be 8+ feet behind the deflector so the air flow will go over the deflector and then drop and eddy in the space between, likely making your mpg worse. Even if you were able to manage a slight increase in mpgs it would take a long time to offset the cost of the deflector.

Yep...when you are moving down the highway the way wind moves is it flows over the lines of the truck then flows DOWN after it moves over an obstruction. If it flows over the cab it goes down towards the bed as soon as it reaches the back of it then creates a sort of vortex in the bed, flowing from there to the tailgate, then bouncing off the tailgate and coming back towards the rear of the cab. If you notice if you were to drive down the highway with a closed tailgate, debris in the bed, and the rear window all the way down, the debris will probably end up floating into the back of the cab for this reason. This is usually how I find out some douchebag threw trash in the back of my truck.

IF the wing is like what the poster said above, the air would probably flow over it then go down behind it and push against the front of the trailer, creating drag and hurting mileage.
