Your comments on gear ratio
I have a 99 1/2 CC 4X4 dually automatic with 3.73 gears. If I had the chance to change complete axles with an identical truck both with around 59k miles, would ya'll recommend changing for 4.10s? The reason I ask is because I can pull a 32' fifth wheel camper better at 75 than 65 or 70 with my 3.73s. It seems at 2000 rpm or lower, any hill pulls me down but I can better hold my speed if I am running 2200 to 2300 rpm. Any comments?
