Hey all-first post here in the f-150 forum!
I have an 08 expedition (King Ranch) 4x4, and its got freakin 3:31's in it. I tried to tow a 20' boat for the first time a few weeks ago and was a little dissappointed. It worked ok in tow/haul mode, but it would be a little happier with 3:73's I think. Any one made the switch? I would almost bet the fuel econ may get a little better? I can't even set the cruise a 75 and not get a downshift on every little hill! (Empty!!) It's got the reciever hitch, but not sure if its got the trailer tow package. I'd have thought it would've have a lower gear with the package?
What gears to use? Rough price? Satisfied?

Any help/suggestions would greatly be appreciated!

Thanks guys!
Mike
