This truck works fine. We have had it six years since new, great towing vehicle and people mover, mileage not too bad as it got older/broken it. I get around 19 or so on highway and 14- 15 in town - not bad for a really big heavy vehicle that is this strong. Replaced an axle seal and air compressor, and normal wear items. I'm keeping mine, no need to trade it.
Power and room for family and luggage. The third row seat gets used a lot. Great trip car.
Air system for LLS is not well constructed or easy to work on, but it's doable. I'd get a better compressor supplier if I were Ford.
