I'm contemplating buying a 2500 ram from a friend of mine with 4.10's. I never tow anything so I don't really need the pulling power so I was thinking about swapping in either maybe a 3.31 or a 3.56 to get better mileage. My friend says he gets about 16-18 and I'm hoping to get low 20's. What does everyone think of this and what kind of mileage do you think I could expect to get?

You have to know what tire size you have and what RPM you are doing in high gear at the cruising speed you drive at. Then you can ask a gear shop to give you the spec's on different ratio's and tire sizes. Putting in a lower ratio, or larger tire's that have you running to low an RPM is not good for the longevity of the motor. I have seen people put on larger tires and the unit will no longer drive in high gear. Get the information ask the people that know, then make you decision. PLAY SAFE!
