Getting a Gear Vendors or US Gear gearbox isn't going to pencil out very well, if you are hoping for better mileage. If you have several grand burning a hole in your pocket, or need more gears for towing, than go ahead and get it if you want.
Would probably be cheaper to do a gear change in the diff(s), or go with some even taller tires.
