So I got my NV4500 installed last week, just intime to go up to Pincrest to go camping. It shifts so easy, the hydraulic clutch is really nice, and the best part is that I went from 7.5 mpg to 12 mpg!!!! And that was uphill. I know a little bit of the mpg increase is from putting on the 38's rather the 42's, but still. I am so happy!! What a difference OD makes!!
