Change Differential Gears to new Ratio?
Has anyone changed the differential gears in their MH to a different ratio? Our 1999 Brave is geared way too low for how we use it and my thought was that I'd get better mileage with a higher ratio. ...

The 454 and especially the V10 both need to rev to produce their optimum power. Lowering the engine rpms by reducing the gearing is not what you want, with these gas engines.
While diesels are comfortable cruising at 1500-1800 rpms, gas engines are comfortable cruising at 2000-2500 rpms and won't see an increase in fuel economy by making them cruise at a diesel rpm range.
The gas engines don't have the low rpm torque that diesels have, to be able to cruise efficiently at the diesel rpm range.
