In my opinion, you don't really need a true high output alternator if you're only running stock electrics. That doesn't preclude the possibility of the current alternator failing and being in need of replacement.
With respect to the voltage gauge in the dash, it is adjustable. When you pull the pod and gauge assembly out, there is a small dial on the side of the volt meter that can be adjusted so that the gauge matches the true volts. I did this on mine, using a reference source and multi-meter to confirm the voltage, and it is now spot on. I also have a TPMS receiver plugged into the cigarette lighter that displays voltage, and it matches the dash gauge.
I don't know for sure if this is true for all years, but it's true for at least '87+. I would assume that it's true for all years, though.
