QUESTION: Would investing in an "Aero Shield Wind Deflector @ $400.00 worth the investment? Cost/benefit? Anyone have any practical experience?

(Forum search... but did not see any information on the topic.)
We have a 2014 combo: F250 Super Duty and Cougar 327RES.

Planning a cross country trip in the next 12 months.10,000+ miles.
Pre-planning includes a full 5th wheel undercarriage inspection, brakes, bearings and new tires, under belly coroplast service/inspection etc.Plus pin box and fifth wheel inspection.
TV is getting a full maintenance inspection.

Looking for some input on the merits of investing in a wind deflector.

There have been plenty of debates about these over the years and the general consensus is don't waste your money. The way a typical FW is set up, there's not any real advantage to them. Some report a small mpg increase, others report less turbulence, but the vast majority report only a PITA. They work for semis due to the fact that the trailers tend to be a =lot= closer to the rear of the cab than 99.99% of RVs, thus literally "drafting" the tractor. There's simply too much distance (research shows that > 18" space, efficiency goes down drastically) between the cab and the front of our RVs for these to really work well. That said, a FW will almost always get better mpg than a comparable TT and adding a bed cover or camper shell to your truck =can= show decent mpg improvement.

They are $285 on Amazon.

I hardly ever see those. Over the last 13 years of full timing. Don't think they are very popular and it's probably because most don't believe they are necessary.

Have you talked to some owners and found out what the benefits are?

My understanding is IF you could put the whole unit in a Wind Tunnel and adjust the Deflector/Wing you might gain something. But just sticking it on the roof of the TV could actually increase fuel useage. To me, much more trouble than any possible gain.

Keep in mind when you are just driving the truck around, it will hurt your MPG.

But yeah, not much to gain and the semi comparison doesn't work as the spacing is drastically different.

Benefit......
Moves the 'bug line' higher up on front cap of 5th wheel

Cost.....too much just to get bug line higher


Is it time for your medication or mine?

I will say. For normal RVers a deflector does not make much sense. However for a 10,000 mile trip at highway speeds, it very possibly could be an advantage. And do remember. They fold down when not towing.

I do have related, real world experience with the wind deflectors. I put one on the rear of my Leer shell on a F-150 SCAB. This got it close to the front of my 22' TT. Fivers get a similar benefit as they are so far forward in the bed with the deflector mounted on the cab. I would guess the typical fiver ends up being about as far from the deflector as my TT did.

Did it work? You betcha... had it on for 3+ years and consistently got 1.5 to 2 mph improvement over running with no deflector. While that is not a huge change it paid for the deflector in about one year. Another way you could tell it was sworking was the absence of bugs on the front of my TT - if they aren't hitting there neither is most of the wind. I only mounted it when towing {no resason to have them mounted if not towing} so no downside doing the daily driver thing.

BTDT and it worked {very well} for me.

As always... Opinions and YMMV

If it did nothing but keep my front cap clean I'd buy it in a New York minute. They sand the roads in the Winter here and I got small chips just on the 5 mile trip from the dealership to the house.
