For the sheer hassle that is an nv5600 swap, I wouldn't bother. An nv4500 bolts right in, has a similar low range, and a similar OD.
The extra gear is actually placed between 3rd and 4th gear. The nv4500 has a fairly wide gap between 3rd and 4th, it something like a 35% rpm drop.
To solve this, NVG put a gear between the two in the 5600.
For what you get, and since the 4500 is such a widely known quantity, I'd just bolt in a 4500.

The nv4500 has a gvw of 19000 pounds I believe. Which is in excess of what the gvw of the truck and hauling limits are. A 1 ton from the 90s was rated to tow perhaps 12000 pounds. And the truck weighs 7 as it is.
The 6 speeds had a higher gvw yes, but you are still limited to the rest of the truck, and what it was certified to pull.
As for operation under load, there's not much difference. The 4500 is a strong unit if serviced correctly.
