You can't get 3.73 gears in a DRW on newer trucks.
For the F350, 3.55 is stock, 4.10 is an option.
The F450 is 4.30.
I am going to order a new truck soon and I will go with 3.55.
On my current truck, 35% of my miles are towing, so that is a lot of non towing miles. I want the lower rpm for better fuel economy.
Over 900 ft/lbs of torque, you are going to notice a difference in power/passing etc with no load.
My last truck had 4.30, 6.0L, with about 50% of my miles towing.
That thing only got 12mpg unloaded.
I do agree, I don't buy these trucks for the MPG, but every little bit help.
3.55 will be fine with the load the OP is talking. Unless he is going over the Rockies on a daily basis.
