Just look around, a Chevy or Dodge can never be found towing anything. You can't tow with those trucks. Ford super duty's come with 4 wheel disc brakes, I can tow a 6 ton trailer, carrying a 10,000 pound skid steer loader. You have to buy what works for real men in the construction and towing industry. Listen, 90 percent of all tow trucks built are Ford, case closed. Ford tough to make money, not to look cool and be comfortable, if you want that, buy a Mercedes.
Overheating problem is persistent and common with 6.0 diesel motor. Three times the EGR cooler and Oil Cooler went bad. Three sets of headgaskets in first 100K miles. Coolant is always low because it loses it. This condition runs rampant in this motor. Ford will do nothing to determine or fix the root cause of the problem. Nor will they offer alternate transportation. Three year old truck has spent two months of that time in the repair shop. Ford considers this acceptable and they do nothing to compensate for lost time without work truck.
