[QUOTE=Piwoslaw;175376]The AeroPack claims fuel savings of 15%-25%! So it's better than a full boattail (15%)? Yeah, right.

They state that a roof top cargo carrier increases fuel usage by 15-25%. By using the pack, Which has "no drag" you gain that back. One mfg. of these packs posted here that they were seeing what I remember as a .5-1% increase in MPG. I don't think they quoted that on their website though.
