3.55 to 3.92 is only 2-300 rpms difference. These trucks should have had 4.10's standard imo.
That's the thing though, I am only going to be towing it a couple times a year, 40 miles each way. I just wasn't sure of how well it would pull on the rolling hill terrain with the 3.55's, or if it was hurting the drivetrain any with just a couple of trips a year. In other words, if it costs me 2400 to do this, but saves me in repairs later, I'm all for it.
