Thanks for the info. I don't want to buy a motor with a history of problems. The 6.4 that was introduced in 2008 (I believe) appears to still have issues. When I discovered that Ford was sh$t canning International Harvester and developing their own motor that pretty much said a lot about the problems with International Harvester. Too bad, I like everything esle about the Ford. Oh, and another issue with Ford is the fuel mileage. It is the worst of the group. Looks like Duromax has the most pulling power, and that is what I am looking for.

I like the Dodge, but my experience with them is they have good motors, but everything else falls apart before the motor can wear out.

Keith, I will send you a PM. I am more interested in new, primarily because I am one of those people who keeps vehicles until they die, but I have an open mind.

Mike
