We've got roughly 4,000Km on the truck now. Gas mileage continues to be a sore point, but that's primarily due to driving style, so I can't blame the truck. On the highway, it yields acceptable mileage. It is certainly not wanting for power with the 3.92's, 8spd and 395HP on tap. My wife absolutely loves it, so that's a big plus. Took my dad out in it yesterday for the first time as I was dropping my daughter off for a camping trip and figured he might want to go for the drive. He was really impressed at how spacious and quiet it was. I'm thinking that when it comes time to retire his old Expedition that one of these will be the logical choice.
