Shane,

I also had the Yakima Megawarrior and my mpg suffered by at least 2mpg. I guess the baskets have more drag compared to the box.

Bobby,

which Yakima did you have? the basket or the box?

Those rooftop baskets seem to knock 1-1.5 mpg off

i add a basket to the stock rack and when loaded, thats about the drop i see.
the weight/drag is likely also a factor

I definitely agree with that. The baskets create huge amounts of turbulent air, where as those stream-line boxes would allow a more laminar flow.

I dont really pay attention, but Ive read somewhere that someone documented MPG with and without, and without he got something like only 1MPG better.

I have some pretty substantial fuel economy records that make me very confident with my numbers. I'll post the specifics when I get home but the only way to get even more accurate is to never change anything on a rig except the roof rack. This isn't feasible for normal people who change things like tires, fluids, etc.
