Personally, I would go with a 3"-4" conveyor belt chin spoiler and rear box cavity - no belly pan.

A full 1/4" aluminum belly pan that you describe in later posts sounds heavy, really heavy.

It rolls up to the SUV/wagon receiver hitch on four castor'd pogos,which rise and stow into the belly while on the road.
3-4 mpg.

But I'm fairly confident that making a permanent version of this out of sheet metal could get me around 1 mpg better then before, and possible even more at higher speeds. The open ended kammback is a go!

What do you think?
