Used 2011 F350 6.7. Do I need to purchase warranty?

[F5Pro]

Looking at used 2011 F350 power stroke crew cab to pull my travel trailer. Vehicle has 95k miles. What is the opinion of the forum as to the benefit of an extended warranty for this truck?
Okay. It is not a factory extended warranty. It is an aftermarket insurance policy that covers the turbo and the HPFP, but not the radiator. While I have enough money to buy an '11, I do not have enough to buy a '15-20 without going into debt, which I am trying to avoid.

In a word, yes.

Make SURE it covers the HPFP and the radiator and for sure the turbo. Those are the biggies.
