i guess i should have stated an idea i have come to realise, well it's a consept right now still putting it together. but the closet that alot of expidit trucks have in the back. if you made that way bigger it should do two things or you. one give you more space to put stuff obviouly and the second thing logically would be that it would fill that dead area back there in theroy getting ride of a zone that breaks up your air flow.there by increaseing your mpg now it might not help alot but it's still an improvment i would think
