The faster you drive, the more of an effect it has. We have that same gap behind our cab, only ever drive 55 - 57, and can still break 12-14 mpg+ easily on flat ground with a 53-foot dry-box trailer with nothing in it. At those speeds and that efficiency, I doubt that even if it were closed up by some over-priced product, it would not make much measurable difference.

That gap only starts to hurt your mpg in a measurable way at higher speeds like 65+. On the other hand, a mid-roof truck pulling a dry-box is a problem at all speeds.

I hear that brainwashing crap off the talk shows on the XM radio too. -- Air-tab this and after-market mod that ,... and bla. bla. bla. bla. -- on it drones over and over, sucking your wallet dry faster than anything it can make up for.

I got an idea,.. want to save fuel the most? -- make the truck last its longest? --- SLOW THE HELL DOWN! and plan your trips better so that you can drive slower and don't have to stop. It costs you nothing and puts more money into your pocket than anything else you can possibly do.

--- and we don't haul light freight ...


(from the bottom up)...
Missouri to New Mexico - 8.205 mpg in 813 miles.
Nm to Az - 9.192 mpg in 505 miles.
Az to Ca - 8.90 mpg in 879 miles.
... and on it goes.

Those are real numbers, real freight, 53-foot dry-box trailers thast are not the best maintained, and typical application.

He has many youtube videos that will show you what to do. If #'s are high then Id be looking at the mandate fix........ If you are in Georgia we would be glad to look at that for you and IM sure gearhead or unilevers would do the same.

You're a good man.
You made good recommendations.
And didn't try pressure him into the mandate fix.

Mr Hagg is the best their is. They don't come any better.
