I know these engines have had some serious problems especially the 03-04s, but how are the older one 06-07. Im in the market for a new truck and has bad as this might soundand want a 06 6liter suderduty This is what I want to get, I love the look and interior (if I get it, itll be the King ranch) and it rides good to. Im scared about the engine though, since ealry 6.0liters are turds, but I wont modded it except for exhaust. So Im asking should stay far away or are the newer ones fairly reliable???
