 I bought this truck with the dealer knowing of my intent to use it commercially. I put 7,333 miles on it in 3 weeks with it loaded with 15-16K everyday. In the 7,333 miles the truck overheated 3 times and when returned to Ford, they found that it had a blown head gasket (a known problem with the 6.0 that i was not made aware of at time of purchase). So now I am sitting at home instead of making money with a $56,000 truck in the shop after only being used for 3 weeks. So in my opinion  do not go with 6.0, i think they need to change the name from powerstroke to powerjoke!  I want my Cummins back with 190,000 miles on it with no trouble at all.
