Congrats, you'll love it! I wish they would have put the ecoboost in the Raptor, but that is off topic.
I am surprised how many people buy the CrewCabs around here. I have a supercab and there is a ton of room there and the CrewCabs have an entire foot extra back there. I guess if you have a larger family maybe, I just carry my dog and 8 week old around.
Not sure how many of you have looked into getting a tuner on your Ecoboost's, but the one I have on my Focus ST (4 cylinder Ecoboost 252hp/270tq) is absolutely amazing. The turbo spools faster, makes much more consistent boost, and the fact it adds about 15hp and 80ft-lbs doesn't hurt ;) (233hp / 313tq at the wheels). I also get better mileage with it since it is setup with a more linear throttle mapping.
