No buyers remorse on the Expedition, I just wish Ford would have given me the option of which engine I want. The idea of a turbo v6 is great in therory, until the boost kicks in. The unloaded fuel mileage is tolerable, and actually good when there is no wind on the highway, but mixed is no better the my 2014 F150 5.0 was as I said before. And the towing fuel milage is a joke. I have to run in 7th gear to get 8-9 mpg. 8th or 9th gear and the fuel mileage drops to 7-8mpg. Thats only towing a 6' x 10' enclosed single axle trailer with a 6' interior weighing about 2000-2500 pounds loaded. My F150 got 10-11 mpg with the same trailer, same speed, same roads running in 5th gear (same as 8th in the 10 speed) and I even had one size up tires on the truck. Overall I still really like the Expedition and don't plan on getting rid of it, but it is my first and last ecoboost.
