extang tonneau cover gas mileage

hello. im wondering if these soft tri-fold covers actually improve gas mileage. does anybody have a 6cyl tacoma with this style tonneau and can you give me an answer to my question. will putting a tonneau really improve gas mileage and if so by how much???? thank you all. paul

 

No. No gas mileage benefit for mine. It's also been busted on Mythbusters.

 

no real difference with mine

 

x2! haha ya, Mythbusters!

 

sounds like i got my answer. thank you all. ill probably still buy one because i need to keep material dry in my bed - but i wont hold my breath for better milage. ill let you all know how i make out.

 

I did not notice any difference.

 

x3, on Mythbusters the only product they proved got you better fuel economy was the webbed tailgate! Screw that though, that's too hilljack for me.

 

nope

 

On my 96 tacoma w/ 3.4L - I had a tonneau cover and it did improve mpg by like 1-2mpg overall.

With this 07 4.0L and tonneau, I haven't noticed any differences.

 

I have the extang trifold.
No difference in MPG
If you really want to keep things dry make sure you put weather stripping under the leading edges of the bed rails.
The extangs tend to run a little short on the tacoma. placement will be critical.
Mine was misassembled, I wound up having to move the cross bars. The rears were too far forward, the front too far back. The way they shipped it it would not draw down flush at the cab end.
I also had to place rivets in the corners to keep the plastic piece in its tracks - this is a common problem with extang trifolds. Every second one you see on the road the corners are peeling back.
Not a bad cover if gotten on sale and one tends toward being handy with tools.
I would rather have bought the pieces as a kit and put it together myself.

 

Thanks for the info. Know this is off topic but....
Do you have a picture of the your rivet mod. My back corners closest to the cab are up a little, maybe this is the problem?
Mine doesn't leak at all & fits very well. It comes off & on regularly due to my landscaping business & has held up well over two years of winter/use.
Back to OT bump for the OP.
