2008 4.30 fuel mileage?

I need to know what guys with an f-450 2008 with a 4.30 rear end are getting as far as mpg goes. I'm buying an f-550 and so I've got a pretty good idea on the 4.88 (8-9 loaded and about 12 at most unloaded). Any help would be greatly appreciated as I'm really needing to get this thing ordered.

It would be over 13% increase in RPM. That is significant. It would depend on the speed your traveling as too how much fuel you would use as compared to 4.3 gearing.

Our 450 with a 430 gear gets 9.5 mpg empty at 75 mph. That's ridiculous!

I moved my 5th wheel that's 10,000 lbs last weekend.

Hwy 83, 928 miles. Average was just over 9 mpg. Mileage is over 11,000.

ir your talking about that equipment that adds a second overdrive and a gear between each gear you prob would get better MPG on the highway but i know it cost over 2k not installed.. plus youll need a new shorter driveshaft.... if you do a lot of highway miles i would sat it would be worth it but if you dont save your money....
