Folks, I drive the superslab every day and the penetration of MPG mods is remarkable. Trailer bottom skirts are commonplace and tail treatments are becoming moreso. I'm seeing more supersingle tires.

Next order of business: Streamlining tires. We know what is needed but keep in mind that truckers spend a lot of time checking their tires. a skirt system has to get out of the way quickly in driving rainstorms and snow or the drivers will resist.

I'm also seeing conversion to CNG as fuel. So far, CNG is a favorite of the beer barons, but that covers a bunch of trucks. Why the EPA insists on making the conversion expensive is beyond me.

But before you can do anything with trucks you have to come up with a better container. The standard container dominates everything but air transportation, and as such cannot be supplants for truck MPG alone.
