I honestly don't know any 6.4 owners so maybe it's not as scary as the legends. I'm a 6ohno owner and my experience there plus a SECOND TURBO would make me run haha. Did you get it for a great deal considering the motor? Looks like a dope motorhome toy hauler besides the powerplant.
I think all the 6.4 stories are just THAT just like the JK stories. Sure it has issues and so did the 2008 Ram when the DPF & EGR stuff came out. I had to delete all that crap off mine because it was in the shop 4 times in under 6K miles. I did a lot of reading and talking to other people who have 6.4's and most said as long as you kept up on the maintenance you would be good. The BAD of the 6.4 is it requires more frequent maintenance than other rigs. But as I said I'll start a rainy day fund for it just in case.
Yes considering how rare these rigs are I feel I got a pretty good deal on it. It's the largest model they'd offered and I was looking for the shorter version but couldn't find one. I was going to go a different direction when this one popped up and it was crazy that it was in Everett too.
