Although I drive this truck a lot, 1,000 miles per week, it has always been serviced by the selling dealer according to schedule. Major problems. Transmission replaced before 1,000 miles. Differential wore out by 150,000 miles. Constant electrical problems and total incompetence by dealer and Ford, caused replacement of all engine sensors, vehicle computer, parts of the wiring harness and finally replacement of every wiring harness in the truck to correct problem of truck engine constantly shutting down during driving. Internal odometer lights still turn off and on at will. Electrical problems ran from 130,000 to 180,000 while they played with it.
Like the ride of the truck, interior design is good. Pulls a horse trailer well and effortlessly (didn't start pulling trailer until 190,000 miles, after all problems were resolved at my expense).
