RAM 2500 6.4 Hemi 3.73 gears, Looking for Opinions

I own a 2015 Ram 6.4 with 4.10 pulls like an ox. Love the truck and towing capabilities. I average 16 mpg mixed driving unloaded. I don't think 3.73 will save you much in fuel but trucks with 3.73 are easier to find. If you aren't going to tow over 10k I wouldn't even worry about needing lower gears. Great truck, would buy it again any day. I think it is a great combination if you want to stay away from a diesel like I did.
