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.
I have driven it less than a 1,000 miles and I am very pleased with the performance and comfort of the vehicle. I am looking forward to pulling our 35 foot trailer and seeing how it performs. I have now driven my F-350 about 12,000 miles with most from towing a 35ft RV. I am extreemly pleased with the overall performance. Towing mpg is about 11-12 and non-towing is 20 mpg. The uphill towing is great. I have no complaints except for the engine noise. I have gotten used to it on the highway and don't ever think about the noise. In town, it is louder than most vehicles. I think Ford fixed the noise on the newer models. I hope to keep this gem for several years because I am very happy with it when I am towing the RV. Loaded, the RV weighs about 10,000 lbs. I haven't gone up a grade pulling my RV that I couldn't increase my speed if I wanted to. That's really good. That's not like my previous vehicle because I could floorboard it and lose speed down to 30 mph and have to endure the pokey climb up the slope and still have my engine overheat.
