Are these original miles on the engine?, or has it been inframed at some point?

With it siting for a year, it likely has a lot of lot-rott.

* Have you inspected the overhead cams?

* Is is stock engine and programming? - or has it been deleted?

- What is the rear ratio on the truck and other specs?

- Does it have a PTO for the hydraulics on a car-hauler trailer?

etc.etc.

As far as I know these are the original miles.
I have no proof or evidence of any past engine rebuild, How do I find out ?
The rear axles are 355
I don't know how to tell if anything has been deleted with out taking things apart.
I did crawl under the truck to check the DPF filter, it looked normal. I did however find a DPF filter in the bunk, I'm not sure what this means. Maybe it was replaced ? The previous owner told me that it needed an EGR filter, I'm sure he meant the DPF filter.
The truck has a Wet Kit installed, that's one of the reasons I bought it. The previous owner told me that he spent $4000 to have it installed. I've watched your videos. One of the first things I plan to do is an EGR tune-up.
