The differance is minimal. The NV3500 has a 4.01 first gear ratio. Seems pretty low, but with a 30" tire, it's pretty good.
So, lets pick an arbitrary shift point of 3,000 rpm. With the 3.55 gear, you'll be shifting at about 19mph. With a 4.10 gear, you'll be shifting at about 16mph. Only a 3 mph differance. Not enough to worry about for the extra torque application you'll be gaining.
However, at the top end is where it really makes a differance. With the 4.1 gear, you'll be turning 2000rpm at 65 mph. With the 3.55, you be turning 1600rpm at the same speed.
If you normally cruise at 55-60mph, the 4.1 gear is better. But if you normally cruise at 75-80mph, the 3.55 is better. Your call.
