 I've had my Super Duty for five months and I truly love it. The diesel is so quite. This summer while on vaction we were stopped for road construction and the sign lady came over to talk to us. She commented how quite the diesel was. On that trip we towed our trailer which is 11,200 lbs over two 11,000 ft passes. We had lots of power. The tow/haul feature is really nice. The ride is very comfortable and the truck is a lot of fun to drive. At times parking can be rought.
