Yet, people to discredit what RAM engines state the trucks can do with a given axle ratio. they appear to know a lot more than the engineers that designed them. Chris

Is it any different than souping up an engine that the engineers designed.

The idea of "souping up" an engine is to make that engine perform better. Selecting a higher numerical gear ratio than what the engineers recommend for a particular weight trailer without knowledge of how the engineers derive their values will likely cause the tow vehicle to perform worse..... slower up the hills and poorer fuel economy. I can see selecting a lower numerical ratio than what is recommended .... you stand to gain a little on fuel economy, especially running empty at the expense of a few miles per hour on the odd hill. There are some buyers who are capable of doing the math and calculating what gear ratio is best for their unique application but those individuals are not going to be asking the question on a forum.
