An F450 with 4.88 gears would be a cab-chassis model. The 4.30 gears came on the pickup chassis.
Either way, I'd stay away from the 6.4L unless you hate yourself. The MDT versions weren't really any better. Sure, some of the emissions components were more robust, but the engine-killer problems were inherent to the engine design. I'd only buy one if the chassis were cheap enough to justify a Cummins swap.
The high fuel consumption is also inherent to the 6.4L. You could expect V10 like fuel economy overall, slightly better on the highway, worse in town. On that note, if you're only using it occasionally, why not just get a V10?
