That being the case, would the standard 3.42 rear axel ratio be a hinderance for grades? I was considering the 6.4 HEMI with a 4.10 axel ratio. Never pulled with a diesel before.
This is where the diesel shines over a gas engine. The Cummins develops peak torque in the 1400-1600 rpm range....so 4.10 gears simply isn't needed unless your pulling a 20k-30k trailer such as a commercial hauler/hotshot/etc.
Gas engine develop peak torque at a much higher rpm (4k-5k) ....so the 4.10 gears work out great for them.
