Pickup Cab spoiler?

I see all these wings and spoilers on suv's, and after searching, have found that the ones that FOLLOW THE CONTOUR are worth while, however, may not help a whole lot.

That being said, I didn't find much in the way of these type of things for PICKUP trucks. I know an Aerocap is probably THE best possible solution, however, it does have some drawbacks, not to mention, many people don't want a cap, or already have something, such as I do, since they need to lock up their tools.

So, would putting a SUV type spoiler be effective on a pickup to reduce turbulence?

Links for thoughts and discussion:
A pickup cab spoiler - seems to direct air DOWN behind the cab, which for a pickup, may not be so bad as it would reduce the wake behind the cab. Downside would be, obviously, the drag created by the wing-ish part being higher than the cab.

hatchback discussion starting at post 38 - closest to a pickup that I could find ATM.

This design is mass produced, incorperates a wing and sides similar to a short aero-cap:

Last but certainly not least, this is simply a link to a Nissan Murano site, but the wing really looks like it could be the most promising of all I've seen on an SUV.

I don't know if any would be effectve really, and if they are, how much? If i'm not getting an aero cap, I may look into producing something?

Something like this on top of an angled aerocap might work, not sure if it would effect aero very much though, subaru seems to think so though

Um...this forum is Ecomodder.com.

Yes...that's my thread. There are a few other threads about aerocaps and making yer own. You'll need to define yer goals first before you start designing/building. My goals were aerodynamic, easy access, lightweight, easily disassembled, rear view (important), and low cost. Security is not an option at the moment while I test/find the right format/design that I can work with.

I can say the aerocap has helped as much as the other aero mods. One mod by itself may have a small impact but combined together...they add up to a significant savings.

Kinda like rain...small drops add up to big lakes!

Any suggestion from the links that i have up there? I may start designing something anyways, but the ways to actually test it are limited....

As far as the Lund Razorback...
Quote:
Attaches to truck bed to extend cab line and acts as a sun shade. Gives an aerodynamic racing look to all pickups.
A look won't do squat fer you in the long run. It would be like slapping a turbo sticker on the fender and it automatically gives you 50 extra HP.

As any spoiler design...the vehicle it's going on will determine the best angle/approach. When I put my rainguard (ducktail) on as a basis to keep rain/water from running down in between the cab window and the camper top window, it did it's job admirably. When I took the camper top off and left the ducktail on...I got some really nice MPGs out of just that alone. Tests show that it's not supposed to work but it did in my case. Not sure why...but I got mileage just as good (if not better than) when my camper top was on. Sure it was only one trip (2 tanks) but based on my previous trips with the camper top on...it was as good if not better. All my ducktail was made from was a single sheet of Coroplast that I taped to the top of my cab.

I'm just so baffled that all these new SUV's have these wings and spoilers everywehre, but NO pickups do...
F150's finally put something on their tailgate that resembles a wing.

I guess you could fab it with some foam and then fiberglass it.

After working with the flow illustrator.. I may do just that... and tuft test it. Or, maybe see if i can't find a scaled down matchbox of my truck or something. I did some of that with my mustang when I had it. I would paint it to see colors/tint windows/euro's, rims/etc. But then I can perhaps rig something up for a true water test
