RPM to speed ver gear.

I think they dropped the ball on the gear choices in the second gens. 4.10s are probably a necessity for the guys hauling at or close to max gcvw, but IMO the 3.55s being the only other option are just too high. They're ok for cruising down the highway Empty but that's not the reason I bought my truck to begin with. The 3.73 Would have been a much better option IMO.

With the 35's on my truck and the 3.54 gears I'm at 1250 RPM in OD at 55MPH. I think it was around 1600 at 70MPH but I am not on the interstate going those speeds very much so I don't remember for sure.
