On the other hand, modern semis have a much better design than our combos. They have huge condo sleepers that meet both the height and width of the trailer. The top of the sleeper end up becoming a quite effective wind deflector. There's several inches of additional side fairings behind the sleeper. This works as vertical deflectors, redirecting air around the gap and to the trailer sides. You end up with a trailer gap that experiences very little airflow and almost eliminating 25% of the drag the unit experiences while traveling down the road.

People claim from personal experience that fuel line magnets and deer whistles work, but lab tests have proven that they don't.

I used to get around 6.5 mpg so I figured any little bit would help! Well On our first trip I got 8.5 mpg!!!! I had to recheck my math and the miles. It was for real. The only other difference was new tires on my X (I went from BFG A/T to a more hwy friendly tire), but even with that my mileage without the wing was similar. I even rechecked on the way home and again it was 8.3! And then on our Myrtle Beach trip I averaged 7.9mpg with the mountains I went through out east! By my math I saved approx. $200 on that trip alone!
I also noticed the truck doesn't work as hard to hold speed. It use to kick out of O/D on the slightest hill or headwind! Now it just keeps on pulling until I'm really into the throttle. The key is having the deflector as close to the trailer as possible and at the right angle.
For me, I see excellent results from it's use!
I have basically the same set up with my excursion v 10 , and my results were pretty much the same .

Next to nothing. What people don't understand is that the back of the trailer if just as important as the front.
This is exactly why the 18 wheeler hauling companies are using those "fish mouth" things that go on the back on their trailers.

Here try it now.
This is the link to RV'er who installed one and gives the specs he received regarding mpg, how to install one, pixs, etc. after putting one on.
And there are several more RV'ers feed back too.

I have and use a second hand deflector on my 5er. At a cost of $60 I could justify it at least to myself. I had a diy deflector mounted on top of a shell at the rear with my old TT setup. I felt less turbulence with the TT, the stability increase with a SRW truck and TT made it worth having. With the 5er and a dually truck stability is not an issue.
As stated above the kamikaze critters miss their target more often and have to look for another battleship. The only downside is the surviving bugs are still able to reproduce.

AS for a "topper" they might possibly improve wind resistance a little bit but you'll also be hauling more weight so my best estimate is they're about a push. A TONNEAU cover will NOT increase your mileage any measurable amount as you no longer get the vacuum effect of an open bed with tail gate closed, which is proven to be the MOST economical but the differences are minimal.
