New 2006 3:73 vs 3:55 rear end
I am dealing on a new 2006 F150, never had a Ford truck before, always GM (sorry everyone). Anyway, in the 2006 what's left, the only truck out there with my color and options has the 3:73 rear end. How big a deal is this, I do not tow anything, and use a Truck as a general vehicle, like most would buy a car. Is my gas mileage going to be worse? Will I be cranking a lot more RPM on the highway?
Any thoughts on this would be appreciated, I would hate for this to be a deal breaker, but don't want to make a 30K mistake either.
Thanks in advance.

What engine is in it? If it's the 4.6 you'll appreciate the extra oomph that the 3.73 will give you. If it's a 5.4 you'll appreciate the extra oomph that the 3.73 will give you. It will not affect mileage that much. On top of that, if you ever go to resale then the 3.73 might be a plus, especially if it's got the 5.4.

only 5% difference
Think of it this way, there is only about a 5% difference. If you only use it mostly as a daily driver and the faster gearing of the 3.55 gave you a 100% efficiency in MPG gains (which it wouldn't) you would only loose 1 mpg. This is assuming 20 mpg highway probably a little high so you would gain even less with the 3.55. Bottom line is you couldn't go too wrong getting the 3.73 for the extra pulling power.
