Anyone have any long term experience with this motor,such as towing ,likes ,dislikes. I like the looks of the Super Duty,but did'nt like the 6.0 motor. Just wondering about the new one. Thank you

There are expected big changes that will be occurring with diesel engines in the 2016-2017 time frame so that they can use lower weight motor oils and so get better fuel economy. If I was considering buying a truck with a diesel engine I would buy a 2014 or 2015 model year truck regardless of the manufacturer.
Diesel powered pickup trucks have a lot more problems than the ones with gas engines and both types have problems that will still bring them to a halt or require a trip to the dealer. All diesel pickups have greatly improved in reliability since 2010.
The top selling are still the Ram trucks with the Cummins engines. Ram sells more 1-ton pickups than all the others (Ford, GM, Chevy) combined each year.
The fuel system is the weak point on a diesel not so much as in terms of a failure of the pump as with faster wear of the injectors. With the high pressure common rail fuel systems the fuel and all the particles are injected at from 29,000 PSI (Duramax) to as much as 42,000 PSI and so the particles are striking the metal at extremely high velocity and doing more damage than with earlier systems. The only protection from diesel fuel, which is very dirty by its nature, is a super efficient fuel filter.
The stock fuel filters are not very efficient. Diesel fuel in the USA commonly has 5,000 particles per milliliter which translates to 1.8 million particles per gallon. A fuel filter that is touted as removing 98.7% of particles is still letting 240,000 particles pass through the filter media and into the injectors with every gallon of fuel that is burned.
Replacing the fuel filter more often actually makes the situation much worse as fuel filters (and air filters as well) become more effective with filter loading. There are after market adapters so you can use 2-micron filters instead of the 4-micron OEM ones and these can filter out 90% of the particles that the OEM filters would allow to go into the injectors. With the Cummins engine you do not need the adapter and the CAT filters are already providing 2-micron filtration and they are a third the cost of the far less effective filters provided by Ford and GM.
