I thought about swapping until I was told that they weren't much different in a 5 vs 6 speeds top gear ratios

The difference ..

with 315's ( 35's) and 3.55's would be ..

nv4500 @ 70 mph = 1810 rpm's
vn5600 @ 70 mph = 1762 rpm's

Not a huge difference, but the more gears in the 6 spd makes it easier to tow and keep the engine in its Power range more effectivly .... and preference and avaliablity ..

I agree, go 5 and if you get serious, then grab a 6 spd truck .. just easier and you dont have to re-engineer the truck to make it work ..

Yeah, they both have thier draw backs ... 5th gear nut on 4500 , shafts on the 5600, case has some weakness on the 5600 as well, ( under real big power .. )..
