I agree with the RFC man.
I have 4.30's in my 2012 F250. I listened to all the hype about gearing down for towing.
If I had it to do over again, i would be running the 3.73 and dropping down to 5th when towing.
I personally think that those tow ratings are set up for the folks that just drop it in D and leave it there. It helps the manufacturer out some with warranty issues and psycho issues with the drivers that run all the time in D.
I'm guessing some people don't understand physics. A longer lever makes things easier to lift. Same goes for lower gear ratio. I run mine in D and shift it when and if necessary. It's all about making things easier not harder.
