Gear ratio Help

Hey guys,

53 3800 1 ton DRW.

The truck will end up with a 250 engine
SM420 Trans
8R-19.5's
14 bolt rearend

Question:

Is 4.11 gonna be the desired ratio or will something numerically lower be better or OK. I.E 3.73 or even a 3.42 that I have already.

Probably see more back roads than highways and it will pull a trailer at some point. (3000 lb tractor on the trailer).

Thanks,

Larry W.
