gear changes for better towing
I just took a trip with my new fifth wheel and I am beginning to see that my truck is somewhat lacking in the power department. On even the slightest hills interstate overpasses my speedometer would keep dropping even with the throttle wide open. I don't expect miracles, but I would like to be able to hold 65 while going down the highway.
I am thinking of possibly changing the gears to raise my RPM so that I will have more power at a slower speed. My truck has the factory original 3.55 gears and I was thinking that switching to 3.73 or 4.11 would help. I don't want to spend a lot of money for nothing and I was hoping that someone here has had past experience that I can learn from.
Currently I am running 32" rear tires as opposed to the factory 30" If I go back to 30" it will be mathematically the same as switching from my 3.55 rear end to 3.73. So I may try this as a cheaper trial.
I can hold my speed better running the truck around 68-72mph much better than I can hold my speed if I slow down to 60mph. Engine RPM is the only way that I can explain this.
So what do you think?
