i gained like 3-4 mpg with just a roll-n-lock retractable hard bed cover so i would think a topper would help alot more as long as it doesnt have the step up in the rear.

no noticeable difference. If that is your sole purpose of buying a topper, unless you buy a really cheap used one, I don't think you will never recoup your costs.

Life changes, so roll with it, not against it.

I have a soft top, so I run with it rolled up half the time. I really don't notice a difference in mileage, but it sure is nice to have while traveling. :Thumbup:

nobody here watches mythbusters huh?? they tested this its a hoax it does not work youget more mpg with out it. something to do with the way the wind flows into the bed and out creates less drag??if you build a cover that is slanted from the cab down to the tailgate as someone on here did I believe he has seen gains from what I have read anything else probrablyis in your head or your foot(brick)on pedalthing ya know what I mean.

i remember that episode of mythbusters and the cover gave a slight advantage to an open bed but the best was with the mesh like airgate that replaces the tailgate.
