Are these just snake oil?

    There is a debate about them on a RV page.

    I have no clue.

    If they actually work, I might get them.

    Call me skeptical though.

    I have them stuck to my top and sides of the trailing edge of my 6x10 trailer. I couldn't tell you if has a perceivable improvement in gas mileage. I used to tow my trailer with a V6 Grand Cherokee and now I tow it with a semi V8 Durango, so that certainly didn't improve it, haha :D

    Just going off of their "Simulation" video, I'd say snake oil. It's faked. That's not how bluff body flow works, and vortex generators aren't going to solve it that well.

    Don't really care about mileage. More about wind stability. Especially when a Semi passes you.

    If your truck is properly set up for the trailer you are pulling it should not sway and you shouldn’t need those.. for fuel mileage I say Snake Oil... do you really think those are going to help the sway from a semi? Hell no.... Semi’s sway from Semi’s.. just use your mirrors and prepare...

    Oh I do. When they come they push you first (bow wave), then suck you in (venturi). Good times. :)

    Greater improvement in mileage by just slowing down.

    Well, I work for a large food distributor who’ve tried all the gizmos (tabs, skirts, trailer tails, etc). The fleet mgr says the improvements are negligible. He can track the fuel mileage of a trailer fully outfitted against a trailer with nothing, regardless of what tractor it’s hooked to, and says it’s so minuscule as to not be worth messing with any of it, especially when maintenance of the stuff is factored in. But, upper mgmt forces the outfitting of devices, so they can appear to be a “green fleet” and allows us into Commiefornia.

    As I’ve posted before, in a Class 8/53’ van configuration, each mph is worth ~1/10mpg. Our fleet mgr tracks all tractors, drivers, driver habits, etc and can back the data. I’ve seen it in my own fuel mileage, while chasing the bonuses, as well.

    There always has to be someone getting all crazy with actual data and shit...

    Flooding us with actual facts is not how it's done around here.

    Its like putting a big wing, front splitter and rear diffuser on a Kia Rio, Ford Fiesta, Chevy Spark, Honda Fit. Useless other than wasting money. Got a couple of those ricers rolling around here with similar crap glued to their roofs, trunk lids, rear fenders and c-pillars.

    I remember reading an article in a car magazine where they took a ricer decked out with that crap. With every piece they took off, the car's 1/4 mile time improved. Bone stock config ran the quickest time.
