In my opinion, the deflector may help fuel mileage minimally while towing. I'd make the deflector removal as I'm sure the extra drag will reduce the fuel mileage when not towing.

I agree, if not removable, certainly make it so it will fold down out of the airstream.

I had a 16.5 single axle trailer towed by an 05 Freestar minivan for 4 years. We went to south end of Texas for 3 months each winter for 3 years in a row. The first year on 6000 miles we averaged 12.3 MPG. I looked on the web and everyone said don't waste your money on a deflector, but all the highway tractors have them, so I started looking for one to purchase and didn't find anything made for vans. So I wasted $25 building one from plywood and mounted it on the van's roof racks. Best money I ever wasted. That year we got 15.4 MPG(25% improvement). You can bet I,m going to waste some more money adding one to our new Hemi. I think the main reason it worked so well is the fact that I angled the ends so it clears the full width of the trailer front.

AeroShield Wind Deflector

Catalog Item # 34579
This Item is In-Stock and Ready to Ship

Internet SALE
$319.99 SAVE $70.00

Reg $389.99

This is from CW - Pricier than I had remembered, if it saves15% on fuel, you would have to drive LOTS of miles to make it worthwhile. By my calculations (probably not correct), If you drove 2500 miles, got 8.5 mpg = 294 gal @ $3.50/gal = $1030 in gas - 15% in aero fuel saving = $44.40 Not much but but figure you would have to drive the 2500 miles (FL to CO and back) three and one quarter times to make up the basic cost of the airfoil. It might make sense to build one of .25 marine ply and cover it with fiberglass (heavier than this one, though it could be wider) or, more expensive, cover it with carbon fiber or ONLY carbon fiber www.dragonplate.com has really cool looking carbon fiber pieces but then you would have to drive more miles than I have left in my life - but WOW would it be cool!

I dunno, getting more miles of my piddling little 26 gallon tank would seem like a good idea. Even if the onetime cost of the airfoil didn't make up for it in mile for mile savings.

I would rather put that money towards a larger fuel tank. There is a direct replacement of the OEM tank for the shortbed that increases the fuel on board.

I am glad the new Ford trucks have 36 gal tanks. Still... It would also be nice to save $$$ with reasonable break-even point on any mod.

I agree that the cost of commercial deflectors would offset most or all the savings. But if you use plywood(mine was even used) and paint it you can try it for <$25. I've saved about $700 in two years with that $25. Most of the commercial add on types are less than the tow vehicle roof wide and you can see all the bugs on the outer 18" or so on the trailer front. I tapered the ends of mine to keep the entire front of the trailer clean and eliminate all of the wind resistance possible.

I saw a guy on the highway today witha 5 -er and his wind delfector was at 90 degrees to the truck roof line. the angle on teh trailer was about a 48 to 50 degree angle. he would have been better off without one.
i am gettign ready to repaint mine to match the 2011 Echoboost tow vehicle.
2 or 3 mpgs is 2 or 3 mpgs the government doesn't get

That's what I was talking about. 25-75 more miles per tank.
