gear ratios

70 in 5th is 2000 rpm, looks like it uses more fuel also

That's a big jump, 5th must not be that deep of an overdrive gear...

Ahhh... No direct gear makes more sense looks like I'm going to be getting one with 3.55

I just lock out 6th when towing heavy on hilly road stretches. That stops the annoying hunting back and forth shifts from 6th to 5th and vice-versa. My truck is a 2012 with 3.55's rolling on 35" Toyo MT's. I tow a 5'er that weighs around 13k loaded. The truck pulls it effortlessly.

I ended up getting one with 3.55s
