Question about using a wing

[kinnisoj]

Weve all seen the wing that alot of guys run on top of the pick up and even some semi's. I know its supposed to start the air going up and over the camper and in theroy help mpg's. so heres my 2 questions
1. Do they work?
2. Will the work for a bumper pull or is the camper too far back? Thanks guys

Any kind of aerodynamics will help-it all depends on distance of tow..
Normally,you see that set up on long-haulers,but to the occasional tower,you'll spend more for the set up vs savings...towing 4-5 times per year for 2-6 hours..no real pay-off..

But,that's ones opinion...

I agree. I think the biggest advantage to the weekend warrior is that it would keep some of the bugs off the front of your 5th wheel.

I think on a bumper pull it would just create more turbulence

Do a Google " air deflector /wing with a bumper pull "

looks like a waste of money even for a 5th wheel
not sure I read 1 positive post ?

if you could get a bubble front for your Bumper Pull I bet that would do more if it is completely flat now ?

After reading more about this, it kinda looks like a wash. Some say yes it will help but not enough to pay its self back, others say it wont. I guess if I had a 5th wheel this would be a must do.
I am coming up with a design for a cuatom headace wrack and I was thinking that this is something that would be easy to incorporate in to the system.
I dunno. Im headin to Yellow stone this summer may just have to keep a eye out and see what others are doin...

Don't forget the suction effect at the rear of the trailer. Toy haulers are the worst with their big flat back and any other flat back trailer. You would gain more fuel mileage with a trailer tail. Good info in the links below of how they do it with rigs and 5ers.

I have been trying to do some research on this mod as well. I pull a wedge car hauler and run 2500-3000 a week and any improvement in fuel mileage helps. Of course every manufacturer claims a mileage increase but many other threads on various forums argue that the return on mileage does not equal the investment cost. Most of those statements were by individuals hauling campers on the occasional vacation. If I can gain as little as 1/2 mpg using the wing then it could save me approximately $2000 a year in fuel. Almost worth the investment to see if I can gain some fuel mileage over the course of the year with all the miles I will be driving.

Anyone have any input?
