I would read the fine print thoroughly, several times. It will state, not-so-clearly what is not covered. Most often, the cooling system, exhaust systems and seals and gaskets are NOT covered....and it will also say something like "failed components caused by non-covered parts are not warranted". Well, that sounds like a good way for them to weasel out of most warranty claims...especially on the 6.4L where most major failures are caused by these non-covered systems/parts.
And you will also have to keep very good records and all receipts if you do your own maintenance, as proper and complete maintenance according to the manufacturer service schedule is also a prerequisite for warranty claims.
I say: put the would-be warranty money away, delete & tune with money out of your pocket and maintain the vehicle well....this should go a lot further in terms of longevity and reliability of the vehicle than relying on some piece of paper full of loopholes for the warrantor and no recourse for the warrantee.
