This story is about my dads boss. I heard he swapped out his 6.0l after it needed a whole bunch of work. You know the usual 6.0 problems, and got a new 6.2 truck instead. He was going on a camping trip and sounds like he couldn't wait the couple of days to get it fixed. I know he is happy now and the maintenance he will have to do is a ton less. Like fuel filters, huge amounts of oil for oil changes, etc. All i heard about is decreased mileage but i think the trade offs were worth it to him.
