The 6.0 isn't garbage. With proper maintenance it will make you a great truck. A few mods that will help the reliability (especially if you tune it) are: headstuds, EGR delete, coolant filter, drain the ford gold crap coolant and replace it with ELC-1 coolant, and rebuild the oil cooler. I may be forgetting some things but i'm sure someone else will post with better info than "6.0 is garbage" and "buy a gasser"
