My prayers are for you and your family who are left to feel the pain. Your nephew is without a doubt being held in God's loving hands. I am the father of triplets and know the health issues of twins/triplets. I could not imangine losing one.
I have a 2010 F 350. I have never owned a diesel before and got this one to tow a 32 ft travel trailer. I have put 22,000 miles on it in the first year and have not had any problems with it other then the DPF "regenerating" 2-3 times a week during normal city driving, no towing. Just got back...
