You do NOT need to change from your 4.10, especially with a 4X4. In hilly terrain I would lock it out of OD and use the tow/haul making your 4.10 into a 4.56. In the days of three speed trannies axle ratios were very important but not with a five speed/OD tranny. I agree a 3.73 behind a gas engine is too tall a gear for towing, but not if you had a diesel.
It doesn't work that way. changing gears effectively changes the ratio of each gear in the trans making each much more efficient and useable, that`s why trucks with a lower gear ratio have a higher tow capacity. you can`t simply just "drop a gear" or "lock out O/D". Unless you have done a gear swap you can`t say that is how it will work.
