So mostly the later alts probably maxed out at 105 or 110 amp so not to get too close to the circuit max amperage.

Stock alternators were either 70A or 80A, depending on options and year. The 105A alternator is a near-direct fit from a Suzuki Grand Vitara. The large ALT fuse (100A or 120A, depending on year) is there to protect the WIRING, not the alternator, so it is oversized from what you might otherwise expect.
There are a few ways of doing a high-idle, if that's what you want for winching or other purposes - both mechanically or electrically. You do have to have a way of turning that off most of the time, or the ECU can/will throw check-engine lights for various things.
