Hmmm, I knew 4.10's would be easier on gas. I'll be driving to and from work with my truck and half of that is interstate. It's about 300 miles one way to college (interstate). I do a lot of highway driving, I rarely tow or race, I do off-road...I'd like some power as well, but keep mileage at all possible. Looks like I have some thinking to do.
My vote is for 4.10 with the info you have provided. Same ratio I run now.
