Maybe... I've probably put $400-500 into this thing over several repairs (minor and less minor), and the fixing, tweaking, and tuning is maybe half done. How does this compare to other vehicles in this class? I've only ever been around Toyotas, so I have nothing to compare against.

Not that many of their Japanese or domestic counterparts are still on the road after 30yrs to compare them to, even when purposely abused these are hard trucks to kill.
Outside of an engine rebuild, most of the ones I have restored over the last 12yrs haven't taken much more than what you have spent to make them mechanically reliable.
