Okay so I did a bit of reading and found that going with a 34" might be a bit better but will reduce the gear ratio to 3.10. More difficult pickup and faster top end speed, right? As far as speed while climbing long mountain passes, how will this ratio play out with the 10-speed and 3.0? I read that the 10-speed in 3.31 is like a 6-speed in 3.73. If I could find a truck with 3.55 I'd go for it but the 2021's seem to be few and far between.
