I doubt it really draws that much without an actual test to verify it.

I seriously looked into it last year when I had to replace my alternator,
because I have a couple very high output alts sittin gin the shop, but it
was not an easy swap, and once I got the elect system working right, I
found out that the stock 90 amp alt is way more than adequate even under
very high load.  If you put a voltmeter on the actual alt output, you'll
hardly see it drop at all even with the high current accessories all on.
