All important considerations depending on how you use the truck and what you want and need.

I don't consider 3.73 low for a first gear and 2.95 sounds to fast, both faster than I'd want as first for my 1 ton truck. 2.95 just sounds real fast, I'd have to do some research and head scratching to see what truck I've driven that has a gear like that and then imagine using it as the first gear.
I actually like the first gear on the 4 speed at 7.05 it is useful for tricky situations and getting a load started, or just taking off from a stoplight on a hill without roasting the clutch or being in a rush.
Second gear is 3.6 and quite useable, anything faster as a first gear could be to fast depending on your use, especially if you can already find a need for and like the 7.05 first gear.
