He will seriously argue this for hours

Its what I think but then again I have no use for cars so my opinion is invalid anyway.

Cannot fit 1000 lbs of feed or 5000 Doug fir seedlings in a Prius. Not sure it has a satisfactory towing capacity either.

I could haul a prius flat on its wheels in the bed of my one ton and bury it completely in 'fertilizer' so no it's cargo space and towing capacity won't cut it for me. I could probably also haul two on a trailer behind it while hauling the third and the load of sh*t on top. I believe the motor in my truck is heavier than a prius too. Not sure though.

Power stroke?

No, good old fashioned big engine 1971 chevy with a 454 to be exact. I like the older trucks, easier to fix of you can find the parts.
