DMAXRIG you are right, my dad who is a die hard Ford man said if the 6.4 craps out like the 6.0. Ford can say goodbye light duty diesel market. And yeah you are right the D-Max is the only one that stayed the same size, but the only reason I have had mixed feeling is the constant change. LB7, LLY, LBZ, LMM in only 7 years, but that may have been improvements and GM just wanted to distingiush from the ok that model engine had this problem and was fixed on the rest sorta deal. The next rig my family purchases might be a D-Max, or another Cummins(depends on what the wife wants since it would be hers). But not a Ford, not right now anyway, the 6.4 would have to prove itself.
