We did the standard 3.5 V6, the 2.0 Ecoboost isn't enough motor for that heavy of a rig, IMHO.
I dig the Sport, but it's overkill for her hauling the kids around, neither of us wanted leather in the Vegas summer, so we decided that the XLT was right for her. We went Sterling Gray, with blacked out windows, and a light tint on the tail lights to blend it all in.
Besides, I just bought a '12 Wrangler if we need 4wd to go anywhere.
Good choice on the color, I had a Red Candy F-150, and it was great!
