Jim,
My younger brother is a diesel mechanic. He also owns and loves his Isuzu Pup pickup truck. He bought it used many years ago with around 60K miles. He now has clocked well over 500K miles on this vehicle and absolutely will not part with it. The body is in deplorable condition but the engine extremely dependable and has never left him stranded. It by no means is a speed demon but he drives this regularly (while is much newer Ford sits gathering dust in his driveway). I would look outright at buying an Isuzu diesel truck and not worry about any engine swapping. Good luck finding this vehicle because as I understand it, the owners are not willing to part with those trucks (apparently for a good reason).
