I live and work in Mexico so decided why not purchase here. I made the decision a few months back when I went into my local Ford dealer. One of the first things I noticed when looking at the truck is that it is built at the Kentucky Ford Truck Plant just like all those in the US. When I opened the fuel door I had a real surprise. No DEF tank or fluid to fool with! Since it is retrofitted for Mexico, it doesn't have all the US required emissions stuff attached, and I suspect will never do a regen! Since Mexico is still on high sulfur diesel fuel, it will run fine both north and south of the US border. I am really looking forward to see what kind of fuel economy this baby will turn out. I have a trip scheduled to the Midwest in August-September so that will give me a good idea. Presently have 123 miles on the clock.
