Question Differential Gearing 4:11?

The truck I have is in the signature. I have 15" 305's with 3:42 gears in it and was wondering if it would be advisable to change them, and if so to what? The reason I ask, I was towing a very light load the other day and noticed it took a hell of a lot to keep her up to speed on some of the SOCAL mountains, and outside of general horsepower, would my ratio be more of the problem than I originally thought, also my gas mileage is crap, but it is a 350, but the pulling really got my goat. Thanks for any input!
