    Does a topper get you better gas mileage?

    Nope, i'd say its a wash once you factor in the added weight.

    I wondered about that since it does improve aerodynamics.

    But I wouldn't know, as I bought mine used and it came with it...

    Sure it probably does fractionally increase the aerodynamics, but it also fractionally increases the weight. So it really probably wouldn't increase the mileage at all. The biggest aero killer is probably the relatively large flat frontal area and under car aero.

    I started getting 1-2 mpg more, but it also coincided with getting new tires.

    So I have no idea.

    The standard response from a topper salesman is, "oh yeah, you get better mpg"

    Pretty sure there is a mythbusters about this....
    No topper, tonneau, or mesh tail gate works. The thing is that the tailgate doesn't block wind. It creates a "wind bubble" that swirls around in the bed allowing air that leaves the roof to flow over the box completely.
    So a cover won't help, if anything the weight will hurt the milage but it would be so minimal you wouldn't notice.

    Myth. Aerodynamic properties of a pickup truck are best preserved with an empty/uncovered bed with the tail gate up.

    Source? Sorry but have to call BS. I've tracked my MPG since day 1 with and without the tonneau making roughly the same drive daily and a light foot. Typically I get 1.5 MPG better with it on.

    Mythbusters did quite extensive testing on how the tailgate creates a swirl inside the box allowing air from the roof to flow directly over the tailgate.
    Tonneau covers are actually the myth, great for hiding valuables though
