I would leave thee 4.7 totaly stock and step up to the 5.7 or CTD.
You don't have the displacment to turn 456 gears, esp when towing, Drag racing performance will be outstanding, but only on the bottom end.
Lose the 20 in rims and your mileage and towabilty will increase ( don't know standard rim size on the 1500 )
My 2500 hemi with just a 373 lt slip tows extreamly well, not better than a CTD, but good.

RE: 4.10 OR 4.56
The most popular differential gear ratios of all time
are the 3.55 used by Chrysler, Dana, Ford, many others
...which has 39 teeth on the ring and 11 on the pinion
http://www.drivetrain.com/chrysler9.25.html
and the 3.73 which has 41 teeth on the ring and 11 on the pinion
and was long General Motors favorite ratio for their engines with shorter strokes
11, 39, 41
those are very special numbers.
What is special about them?
What are they called?
What does using that special number of teeth have to do with vibration and wear life?
Do 4.56 gearsets have the advantage of that number of teeth?
