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.

My 1965 C10 1/2T came from the factory with a 2.95 first gear and a 3.73 rear diff. It had a 3 speed column shift MT. I think a 12:1 combined ratio (2.95 X 4.10) for 1st gear should easily get a 1 ton moving without slipping the clutch. Under heavy load, I'm not so sure. Perhaps the S10 T5s with either a 4.0 or 3.75 first gear would be OK. I guess it depends on the driving conditions.

For me, the biggest issue is that I'm not so sure the S10 T5 is strong enough for the task.
