Tonneau Cover and Fuel Economy

[dieselknudt]

Does any one know if you gain any MPG's by adding a tonneau cover to your truck.
I want one but I would like to have a good reason to justify it!!!

I've heard it's just a myth but I disagree. I can't give you any exact numbers but I think I've gotten better with compared to without driving in the same situations. And it only makes sense really .... I also know I got at least 1 or 2 mpg with the tailgate down. If there is stuff in my bed like now i have a whole wieght set with a bench n' all the pieces and everything since I brought it down when I moved and realized I have no place for it then I have my tonneau on. In the winter of if I'm scrappin I have my topper, cause in the winter my soft leather tonneau ... if I unsnap it for any reason lord knows i won't be able to get it back lol. Otherwise I just leave it off cause I like having the room in the bed when I need it.

It might save a little bit of fuel, but It definitely doesnt justify the cost of a tonneau cover .

MmmmThat depends on what you get! A soft leather tonneau cover snap style in great condition off of a Chebby longbed that fits if you line it up and clamp it JUST RIGHT for $40


......... Or an aluminum Topper off an OBS that fits if you line it up and clamp it JUST RIGHT and take off the tailgate cap so it will close. It was on it's way to the scrap yard and bought for $20! Just put a coat of rustoleum on the terribly faded top.

I put a soft tonneau I got off ebay on my truck before I drove 10 hours from KY to NC, my mileage did improve a few MPG's.

If Dave is on here... he has the powerstroke that gets about 26-27 mpg.. he claims it makes a difference.. check it out... read through this.. I think it is near the end...

i have 1 for sale!!!! i've noticed about 50 more miles to the tank.

I havent tested it on the 06 but with the 01 I gained about 1.5 mpg

I disagree, I've documented my mileage from day 1 as I drive a lot on the freeway to and from work about 85 miles a day. The cover I have took my mileage from 17.5 to 18 max to 19 average and that's every tank after the cover has been on (the last 20k miles). This is not a fluke as I've not done any other mods since. If you're serious about getting maximum mileage this is a must in my opinion..well that and a light foot!
